Sooner or later, Iran was going to be forced to change its tactics, but perhaps not in the way the United States intended.
Ever since he withdrew the United States from an international nuclear agreement with Iran in 2018, President Trump has been provoking the Mideast country with more sanctions and an increased military presence. The idea is to make Iran buckle.
Instead, it has recharged its nuclear program and become more aggressive militarily. In the wee hours of Thursday, Iran shot down a U.S. surveillance drone that it charged had veered into its airspace. None of which is surprising. When backed into a corner, you fight back.
