You keep mentioning avoiding war:
Like Korea, Viet Nam, Serbia/Kosovo, Gulf War 1, Gulf War 2, Afghanistan, and I’m sure I’m missing a few.
Some success their avoiding war.
All of those wars you mention were local affairs and while some of them were bloody they did not spread and the war lost was in thousands of Us soldiers instead of the 100,000 ‘s........
Your way leads to bigger more deadly wars. It is a proven historical fact. The world will fill vacuums in power. If we do not lead others will and those others will more than likely not have peaceful intentions....or do you think this one time in the history of mankind it would be different?
