President Donald Trump claims that the United States has, in his words, “completely decimated” Iran. But the situation appears more complex, especially with two U.S. warplanes just having gone down in separate incidents during the war. Trump has struggled to respond to Iran's actions such as effective closure of the Strait of Hormuz that's disrupted global oil supplies. His go-it-alone approach has faced criticism from traditional American allies reluctant to support a war they didn't endorse. At home, some Republicans emphasize the importance of maintaining strong international relationships and are taking issue with Trump's unilateral strategy.
