As a presidential candidate, Donald Trump promised to put some reasonable limitations on how the United States conducted its post-9/11 wars across the Middle East.
"The legacy of the Obama-Clinton interventions will be weakness, confusion and disarray, a mess," he said in April 2016, during his first major speech about foreign policy. "We've made the Middle East more unstable and chaotic than ever before."
Since taking office, Trump's track record has been decidedly mixed. He launched missiles into Syria. He ordered American troops home from Syria. He then reversed himself and sorta-kinda agreed to keep them there for a while longer.
But on Tuesday night, Trump unambiguously backed Forever War. He vetoed a congressional resolution that would have ended American military involvement in the Yemeni civil war—a conflict that has killed an estimated 50,000 people (scores more have died in a famine triggered by the conflict) without having any significant bearing on U.S. national security.
