Despite Trump’s flaws - of which there were many - he does deserve the label of Trump the Peaceful. Zero new wars started during his administration; he pulled out of Afghanistan (globohomo delayed the actual withdrawal until Dementia Joe entered office so he could claim credit for it as globohomo pivoted to the Ukraine forever-war), tried to disengage America from Ukraine, and even the small-scale attacks he felt forced to engage in (such as bombing an empty Syria airfield) were very light. There were also basically no domestic terror attacks initiated by the CIA/FBI under his administration.
Trump the Peaceful is also a pretty funny label.
