Wasn’t this already tried? Wasn’t it called the Cold War and didn’t it NOT WORK??
You are absolutely correct. But in liberalhood, there is this perverse idea that the U.S. is the cause of conflict in the world, and in order for there to be peace, there must be military parity. That is why they want to diminish the U.S. military in remove the temptation of the U.S. president to use it.
Of course, the U.S. combatants would pay with blood for this idiocy.
