Trump weighs military action against Iran as Tehran braces for strikes

President Donald Trump has threatened to "blow the entire nation up" amid rising fears of a new phase in the US-Iran conflict, saying he is in "deciding mode" over potential strikes on Tehran. Iran's highest operational military headquarters claims intelligence suggests Washington is preparing to resume attacks, and Tehran has put its military on high alert. Trump outlined three options in a Fox News interview: wiping Iran out, economic strangulation, or making a deal. The conflict has already spread, with Iran-backed Houthi rebels firing a ballistic missile at Saudi Arabia and threatening countries supporting US action. Iran has vowed retaliation against American bases, while the US has issued security warnings to citizens across the Middle East.
