@mike_kraft Iraq I, Vietnam, and Korea were very directly policing. Many of the Cold War conflicts were indefensible in my view, interferences in domestic politics, analogous to the Soviet Union in Czechoslovakia. Nevertheless, for all the error and horror, territorial war, the great scourge of history, outside of Africa (which the US mostly writes off as too troubled to bother which) has been deterred since WWII. Which is why Ukraine matters so much.
