How do we know we are not being brainwashed by the "support our troops"?

I was thinking that people normally don't kill others for fun, and a military is an organization that specialize in killing. Even Nazis, weren't born to hate it was learn and Hitlers army was following orders. But to them they believed they were getting the enemy, just like we do. With that said how do we know that we are NOT 'bad' guys when we go to war? Anytime you support our troops" no matter what" then you are more likely to be deceive, whether the threat is real or not, we will blindly support it, or be labeled unpatriotic.
