No war was waged under Jimmy Carter, the 39th President of the USA. Although Trump did not start any new wars, he continued several wars.Former US President Jimmy Carter has three great achievements under his belt: he forced through the Camp David Accords, one of only two peace treaties that Israel has ever signed; he also forced through the Panama Canal Treaty, a deeply unpopular move at the time that returned the canal to Panama, but which prevented, many believe, a war in Latin America; and he brought in an energy policy that saw him reduce America's dependency on imported oil by half. Carter Didn't lead America into a war.

Despite pledging that he would stay out of foreign wars, President Donald Trump escalated wars in Syria, Afghanistan, and Iran. In 2017, Trump announced that he would send more forces into Afghanistan. Trump also deployed a sizeable number of American combat forces in Syria. Trump gave former Defense Secretary Jim Mattis, a free hand to deploy US ground troops and step up the air war against ISIS in 2017. Trump dispatched hundreds of new US troops to Iraq and also put them closer to the front lines and gave them more freedom to bombard targets from the air. Trump has also tweeted about launching a preemptive strike against Pyongyang if it continued to threaten the US and its allies.
