You have a much more optimistic outlook than I do.
Soldiers follow orders. History has shown that they will do so even for the most horrific things. The US military is not staffed by saints.
Let me explain my optimism regarding an operation of this nature. First off it would happen during peacetime meaning that any bloodshed instituted by the aggressor spells murder. Blood that’s shed by the aggressor spells self defense. How many people are ready to murder? Especially a fellow American.
