How to Survive World War 3
(June 2025 Update: Iran‑Israel Confrontation and Global Fallout)
In June 2025, Israel launched a series of strikes on Iranian nuclear facilities, prompting Iran to issue direct threats of retaliation. This sudden escalation marks a significant geopolitical shift and introduces a new global flashpoint. The situation is no longer just a regional skirmish: it risks spiraling into a broader war, with the U.S., NATO, and Iran’s allies signaling readiness for involvement.
Experts warn that this confrontation may accelerate the risk of World War 3, particularly as global powers take sides and tensions ripple across oil markets, defense treaties, and diplomatic channels. According to international news reports from Al Jazeera, Iran has vowed to "respond decisively" if further attacks occur, igniting fears of superpower conflict and nuclear threat. For more Live updates on this news, here are on the clock reports from Reuters and The New York Times.
This unfolding crisis adds urgency to global preparedness efforts and reinforces the necessity of individual readiness. (See full conflict breakdown in “Which Countries Are at War Right Now?” below.)
In today’s uncertain climate, discussions around World War 3 seem more pressing than ever, especially as global dynamics shift. While none of us can truly predict the future, preparing now can make all the difference if a WW3 scenario were to unfold. This guide is a reminder that, should such a crisis arise, taking precautionary steps can help you and your loved ones survive.
What Countries Could Be Involved in World War 3?
While predicting the exact lineup of a global conflict is difficult, leading analysts suggest the U.S., Russia, and China are the most likely central players. These nations wield vast military power and have a complex network of alliances. As of June 2025, the Iran-Israel conflict is a new flashpoint that could rapidly escalate, drawing in these superpowers either directly or through their regional proxies.
Other regions of interest include Eastern Europe, Taiwan, the South China Sea, and North Korea.
Knowing these potential flashpoints is essential for preparedness so you can ensure that you and your loved ones are safe.
Which Countries Are at War Right Now in 2024/25?
As of mid-2025, several major conflicts dominate global headlines:
- Russia-Ukraine War: Ongoing since 2022, this war has intensified with no clear resolution. Western support continues to bolster Ukraine’s resistance.
- Israel-Palestine Conflict: Following Hamas's October 2023 attacks, Israel’s military operations in Gaza remain aggressive, now compounded by the June 2025 strikes on Iran.
- Iran-Israel Escalation: Israel’s preemptive strikes on Iranian nuclear sites in June 2025 are a major development. Iran’s response could draw in allies like Syria, Hezbollah, and even Russia.
- Sudanese Civil War: Renewed violence since 2023 has displaced millions, collapsing infrastructure and deepening humanitarian crises.
- Myanmar Civil War: Rebel groups continue to resist the military junta, with international concern growing.
- Haitian Gang Violence: Widespread gang control has rendered large portions of the country ungovernable.
These conflicts represent some of the most intense and devastating situations currently unfolding around the world, and despite being localized, they represent significant geopolitical risks. Other regions, such as the South China Sea, Taiwan, and North Korea, also pose ongoing threats that could escalate into larger-scale military confrontations.
How Close Are We to World War 3 in 2025?
Predicting the likelihood of World War 3 in 2025 is difficult, as global conflicts are influenced by many unpredictable factors.
While global leaders stress diplomacy, the world has arguably not been this close to a large-scale conflict in decades. The Iran-Israel tension in June 2025 significantly raises global risks, especially given Iran’s alliances and the U.S.’s historical involvement in the region.
Combined with ongoing conflicts in Europe and Asia, cyber threats, and economic instability, the possibility of global escalation is more than theoretical. Preparation is no longer a fringe concern.. it’s mainstream necessity.
Additionally, economic instability, cyber warfare, and competition for resources could further heighten global tensions. While diplomatic efforts are in place to avoid large-scale war, current geopolitical dynamics show that the threat of conflict remains high, but it is impossible to say whether it will escalate into a global war.
By the time you NEED protection, it is likely too late. So, it’s time to revisit prepping for “Doomsday” once again. Doomsday preppers are far and wide for good reason; each day another conflict appears to arise around the globe. And unfortunately, WW3 will most likely come at a nuclear cost. So, what are some essentials you need to survive a potential WW3 and nuclear blast breakout? We broke it down into 4 sections – how to prep for nuclear war, what you need in your survival kits, how to survive a nuclear blast, and what to do after a nuclear attack.
And remember to get your gear today BEFORE a blast occurs. Better to be safe than sorry.
How to Prepare for WW3 – Updated Tips
As the global landscape changes, the best practices for how to prepare for WW3 also evolve.
“Doomsday Prepping”
A nuclear blast can and will be devastating. The doom and gloom is why a lot of people don’t prepare for it. However, in today’s climate, we have enough advancements in technology to start anew, should we ever come under attack. But you must be prepared for worse. Are you new to prepping? If so, check out our introductory guide to prepping here! Three things to look into TODAY:
- Start preparing your emergency survival kit. Now there are tons of stuff you can hoard for a bad day. This may include non-parishable goods, water, battery powered radio, secluded energy source, flashlights, batteries, etc. See our next section to get an in depth look at what you may need and where to buy them,
- Locate a safe place to stay during the blast and to store your goods. Now this is going to be more difficult than the first one. See if your community has designated fall-out shelters. Identify these and look into getting on a “list” to make sure you can go there in case of an attack. This website has great insights into finding shelters near you https://www.skilledsurvival.com/fallout-shelters-near-me/. If there are none, next best option are windowless structures and basements / cellars.
- Create an Emergency Plan with your loved ones. Make sure everyone is aware of where each of you will be and where to meet up after a nuclear event. Sometimes not knowing if your family is OK is worse than enduring the event yourself. Strategize and figure out each person’s nearest shelter to their home, local grocery store, work, or school. Keep the plan with your emergency supplies and update often (1 to 3 months).
Where is the Safest Place to Be if WW3 Starts?
Determining the safest place during World War 3 depends on the type of conflict and its global scope. However, certain areas are generally considered safer.
Neutral countries: Nations like Switzerland and Sweden, which remain neutral in conflicts, are often seen as safe havens. These countries are less likely to be directly involved and typically have strong civil defense systems in place.
Remote areas: Regions far from major cities and military targets, such as New Zealand or isolated rural areas, could offer more security during widespread conflict. These areas are less likely to be drawn into combat zones.
Underground bunkers: For those seeking protection from extreme scenarios, underground bunkers designed to withstand nuclear or biological threats can provide a high level of safety. Equipped with essential supplies, they offer shelter during long-term crises.
Ultimately, safety will depend on the nature of the warfare - whether nuclear, conventional, or cyber - and how the conflict unfolds.
Strengthen Your Shelter Options
Building on the importance of fallout shelters, new data suggests that concrete bunkers with internal ventilation are most effective. If you have access to an underground or reinforced location, such as a basement, consider upgrading it with extra concrete layers.
"What would happen if World War 3 started?" Preparing to take shelter in areas with fewer windows and air leaks can significantly increase your chances of survival.
“How to survive WW3? - Survival Kits, Survival Gear, and Emergency Kits”
Now you got your plan, let’s get you your supplies. There are a lot of things you could get, and here is a general list. Luckily, most of this stuff can be purchased online (and found on Amazon). Attached are links to some of the goods on Amazon. Links will open up in a new window on Amazon (affiliate links may apply, where we get a small commission if you click the link and purchase).
Gas masks and Filters - Prepare for Chemical and Biological Hazard
In WW3 scenarios, chemical warfare is a recognized threat. Equip yourself with NBC-rated masks (Nuclear, Biological, and Chemical) and filters designed for such events. Chemical attacks introduce hazards like mustard gas, so ensuring you have CBRN (Chemical, Biological, Radiological, and Nuclear) filters that can last up to a week is crucial.
In a World War 3 scenario, chemical and biological attacks are a real possibility. Equipping yourself with full-face respirators that meet NBC or CBRN standards is critical for surviving airborne threats like tear gas, nerve agents, and radioactive particles.
Here are top-rated options from Parcil Safety:
- IIR-100 Recon Gas Mask — Made from butyl rubber for superior chemical resistance, this full-face respirator is ideal for high-risk environments. It comes equipped with the NB-1 40mm DefensePro Filter, offering broad-spectrum protection against nuclear, biological, and chemical agents. Its rugged design ensures a secure seal and extended comfort for long-duration use.
- CS-100 Riot Control Gas Mask — Designed for civil unrest and tactical deployment, the CS-100 provides full-face protection from riot control agents such as tear gas and pepper spray. It pairs with the NB-1 Defense Canister, a trusted 40mm NATO filter designed for fast-acting threats, making it a reliable choice for emergency kits and rapid response scenarios.
- NB-100 Tactical Gas Mask — This flagship CBRN respirator ensures a tight seal and rugged durability. Its 40mm NATO compatibility gives you flexibility to switch filters based on evolving threats.
-
40mm NBC/CBRN Filters — Remember, the mask is only as good as its filter. The A2B2E2K2P3 R D filters are designed to protect against organic gases, acid gases, ammonia, radioactive particulates, and more. Filter longevity depends on exposure level—always monitor and replace as needed.
Iodine and Other Gear
-
Iodine is an effective treatment for radiation exposure. Iodine, ((KI) potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine.
- Depending on your age, weight, and exposure level you will need to take different dosages of KI to protect yourself. See the chart below for a better idea of how much you need to have stocked.
Age Group KI Dosage Number of 130mg Tablets Adults over 18/yr old
130mg 1 Over 12-18/yr and over 150lb
130mg 1 Over 12-18/yr and under 150lb

Improve Your Emergency Kit with New Essentials
Supply needs evolve as technology advances. Beyond basic needs like food and water, consider adding modern tools to your WW3 survival kits:
- Power Banks and Solar Chargers: As reliable power sources could be disrupted, solar-powered banks will ensure your devices remain usable.
- Portable Water Purification Systems: Look for compact and effective filters; some portable options can now purify hundreds of liters, ensuring access to clean water when needed.
- Digital or Hard Copy Maps: During World War 3, online navigation may not be dependable. Having access to physical maps of your area is vital.
“How to Survive a Nuclear War/blast?”
If its coming, its going to be quick and hectic. Follow these steps if a nuclear attack is on its way:
- Listen to official information via online, radio, or TV and follow all instructions provided by the emergency response personnel. Grab your NBC or CBRN gas mask ASAP.
- Locate the nearest building that will provide the best protection from nuclear fall-out and radioactive material – concrete or brick is ideal.
- Get as far below ground as possible. The soil and concrete will separate you from radioactive waste the further you go.
- Expect to stay inside anywhere between 24 hours up to a week. If you have your emergency radio, wait until authorities give the clear to come out.
In the event of World War 3 news or other significant alerts, relying on official sources will be essential. Shortwave and emergency radios are invaluable as they operate independently of internet or cellular networks, which are likely to fail.
“Nuclear Fall-Out: What to do afterwards?”
Unfortunately, with a nuclear bombing, the fall-out and halo effect of a bomb can be just as bad if not worse than the actual bombing itself. Radioactive decay takes years to disappear. So knowing what to do after an attack is vital to your survival and life after.
- Grab your NBC or CBRN mask and put it on BEFORE leaving the shelter.
- Do not go near “hazmat” sites.
- Locate your family and friends at your pre-designated emergency meet up spot (if this was not directly in the bombs path).
- Tune into local and national emergency news casts. Staying up-to-date on the fallout may keep you safe from getting radioactive materials.
- Stay clean and destroy potentially contaminated clothing. Wash yourself heavily with soap and “clean” water.
- Stay positive. Should we ever experience a devastating event such as a nuclear blast, we will all need to band together and lean on each other to make through each day going forward.
If the worst-case scenario occurs, what to do if WW3 starts should be clear in your emergency plan:
- Follow all official alerts: Remain informed by tuning in to official sources, and do not leave your shelter until an official clearance is given. Government-issued alerts will advise on the safety of different areas.
- Connect with loved ones post-event: Nuclear events make communication difficult, so ensure that your emergency plan has a designated meetup point. Knowing where to find each other is critical to survival.
- Prepare for a long-term fallout: Unlike typical disasters, World War 3 or a similar event can lead to fallout that persists for years. Expect to adapt to a new lifestyle where survival skills, community resilience, and resourcefulness are vital.
- Make sure your survival kit is complete: Having all the necessary items in your survival kit is crucial, as each piece plays a vital role in increasing your chances of enduring the challenges posed by a large-scale crisis like World War 3.
I have a saying – “Hope for the best and plan for the worse”. In a best case scenario, none of us will have to use any of these steps. However, its better to be prepared than not. Again, I provided links where you can purchase different stuff and steps on how to find active fall-out shelters near you. I will be updating this page as I can with as much vital information as possible.
