Thousands of protesters flooded streets across major U.S. cities as tensions soared over reports that Donald Trump may authorize airstrikes on Iran targeting the Khamenei regime. With intelligence leaks hinting at a possible January 31 offensive, demonstrations initially organized as anti-I.C.E. rallies quickly evolved into nationwide anti-war protests, questioning the legality and timing of any strike. Over 300 coordinated protests are expected this weekend, capturing global attention as America stands on the brink of yet another potential conflict in the Middle East.
