President Trump campaigned on getting America out of endless foreign wars. But he was also clear that he would let out military leaders fight the war as needed to win it, before leaving. So, at times, Trump grows impatient for the victory he wants to see during his term. In a mid-December 2018 tweet, Trump announced a bit prematurely that the United States was withdrawing from Syria, declaring, “We have defeated ISIS in Syria, my only reason for being there during the Trump Presidency.”
But by the end of December, Trump had backed off a bit, tweeting that our battle remained against “ISIS remnants” as the group was “mostly gone.” He has since decided to maintain a presence of about 400 troops in Syria.
War is always messy. Nobody can ever predict where it will go and by when. The enemy will try to counter in unexpected ways to upset any predictions of victory by our side. It also does not help that American military leadership seems to be indoctrinated over past decades into war management, rather than a victory that would allow a secure troop withdrawal.
But Trump’s short messaging style does prompt others in his administration to try to add clarity about what the administration understands. So, in early March 2019, National Security Advisor John Bolton, in an interview on ABC News’ “This Week,” made the point that the Islamic State remains a threat, and that it is “growing in other parts of the world” besides Syria and Iraq.
