The U.S. has strengthened its military posture in the Middle East, increasing its resources in the region to give Trump the option to join Israel's strikes on Iran if he sees fit. Israel says it struck Iran to stop an active military nuclear program.
Trump is urging Iran to make a last-ditch deal that ends the war. He says he will not allow Iran to build a nuclear bomb, an ambition Tehran denies having, saying it only seeks nuclear energy for civilian purposes.
