U.S. Army In Mideast :Why Do We Wear Uniforms?

We as a nation have been losing wars of choice since World War II. Many of those wars have been fought against locals who just wanted to live in their own country and didn't want us or anyone else interfering in local issues. That's are first mistake. But on top of picking local civil wars to get involved in we make another mistake. We invade these countries wearing uniforms that unmistakenly point out to the enemy who the target is. By the way, the local "enemy " doesn't wear a uniform.. So he has a distinct advantage. And so it goes. How stupid are we?
