Posts on social media say former U.S. President Donald Trump was “the first president in modern history” who “did not start a new war.” There have, however, been other U.S. presidents in modern history who did not enter the country into a new war. While defining military interventions can be difficult, Trump is not the only president not to start a new war during his administration.
