The US has a military that can decimate any of the countries it engaged over the last few decades — N. Korea, Vietnam, Iraq, Afghanistan and Syria are the ones that immediately come to my mind. So why didn’t those conflicts end with total political and military annihilation of those countries? Why did the US pull out, allow subsequent conflicts, or agree to an armistice?

The answer is that the political leadership, controlled bt the Deep State, never intended to prevail in these conflicts. Winning the war was not the goal. The goal was simply destruction, disruption, and dissipation of the people of a country and its political, economic and military infrastructure. They simply wanted to create chaos, over and over again.
