The United States raised its security alert on June 22 after bombing three Iranian nuclear sites, prompting concerns of retaliation from Tehran. Cities like New York and Los Angeles increased security measures, and government agencies issued warnings to citizens. The Department of Homeland Security declared a “heightened threat environment,” and the State Department issued a worldwide caution security alert for U.S. citizens overseas.

U.S. officials praised the military operation, which involved precision strikes using 125 warplanes to shatter Iran’s nuclear program. While Israel supported the strikes, global leaders called for de-escalation to prevent a broader Mideast conflict. Some U.S. lawmakers questioned President Trump’s authority in launching the attack.

Trump suggested the possibility of regime change in Iran, leading to mixed reactions from world leaders. North Korea condemned the U.S. strikes, while Japan called for de-escalation and a return to diplomacy. Oil prices surged to a five-month high following the attacks, driven by supply concerns.

Law enforcement agencies across the U.S. deployed additional forces to protect potential targets, and there were concerns about Iran’s potential responses, including the closure of the Strait of Hormuz. The international community reacted with calls for peace and diplomatic solutions, while the UN watchdog planned an emergency meeting.

The situation remains tense, with uncertainty surrounding Iran’s next steps, as the country has various options to defend its interests. The U.S. strikes on Iran have significantly altered the dynamics in the region, sparking condemnation from Russia and China and raising concerns about potential repercussions and further escalation.
