Nuclear expert Alex Wellerstein identified 15 U.S. cit

Amid global instability, anxiety about war is becoming part of everyday life.

Political tensions, military posturing, and sharp rhetoric have made peace feel increasingly fragile, especially as

“assumptions about long-term stability can no longer be taken for granted” and the idea of conflict feels “more immediate.”

Visible geopolitical moves—such as tensions involving Venezuela and Iran and claims over Greenland—have fueled uncertainty.

Some see these actions as strategic, while others view them as destabilizing.

Although deterrence and treaties still exist, history shows that

“miscalculations and miscommunications can trigger devastating consequences,” particularly in a nuclear-armed world.

Experts warn that a nuclear conflict would not only threaten major cities but also

smaller U.S. towns near military infrastructure, alongside symbolic and economic centers like Washington, D.C., and Seattle.

While disaster is not inevitable, growing public concern reflects fears tied to

“unpredictable leadership, fragile alliances, and advanced military capabilities,” underscoring the need for restraint and cooperation.
