Trump is aware he lost some support with his war against Yemen, and more support with his war against Iran. He can't continue to attack more countries and expect any support at all by the end of his term. The only people left would be the small fraction of people who are pro-war and don't even admit it generally speaking because they are well aware they are a minority of maybe 15% if that.

The bulk of problem base of our society could be described as excessive violence. People use violence to achieve unequal rights in a classed society of ruling and ruled classes. People use violence to get money and power at the formal organizational level, fully government sanctioned. Violence very often achieves the exact opposite of its intended effect, especially violence that is unjustified.

The best path to peace, is peace.
