Yes, the United States will always be at war. Trump waged much less war than what is convenient for a US president and way less than everybody said he would. Compared to other US presidents he was a man of peace. I know the power of denial is much stronger than that fact.
There is a strange paradox with Trump in that he seems like he would start a war just to score ratings or settle a grudge but it is precisely for this reason that I think it would be difficult for him to really effectively lead the nation into the war because unlike, say, a GWB, there would be far too much skepticism over his motives. So perhaps perversely it is his unfitness as commander in chief that kept us out of more significant military excursions.
