In response to the escalating conflict with Iran, security measures across the United States have been significantly elevated. Law enforcement agencies, including the FBI and the Department of Homeland Security, are on high alert due to concerns over potential retaliatory attacks, including the threats posed by sleeper cells and lone wolf attackers. Cities nationwide, from the D.C. metropolitan area to regions in New Jersey and beyond, have intensified patrols and surveillance, especially around government buildings and places of worship. Officials are urging citizens to remain vigilant while also preparing for possible cyberattacks. The heightened security comes amidst a rising number of protests against U.S. military actions in the region, reflecting growing tensions both domestically and internationally. As authorities strive to manage these threats, discussions about the likelihood of further attacks are ongoing among experts and local leaders.
