President Trump’s decision to strike Iran pulls him toward the kind of overseas conflict he once attacked. On Saturday, the U.S. joins Israel in attacks that Trump says stop Iran from getting nuclear weapons. The move clashes with his “America First” message and his past criticism of the Iraq War. Republicans split fast. Some praise the strikes and accept the risks. Others warn against another open-ended fight. Democrats push for more oversight and plan a war powers vote. Polls show many Americans fear Iran’s nuclear program. They also show low trust in Trump’s judgment.
