Wrong how? We quit when we were winning & 100's of thousands of people died as a result.
This time we're in the same position, but the biggest difference is that we have an enemy who has a stated intent to come here. And we live in a world where that is far, far easier than it was 35 years ago.
Iraq is seeing incredible successes in a very short time. The political side is not developing in the way we wanted, but we're getting pretty much the same results we wanted via a different route. We wanted it consolidated at the federal level. Rather than that it's happening at the state & local level. Much as out constitution designed our country to work.
Now, we can give up, hand victory to the people we are beating & give them the morale they need to sustain their efforts against us, with all that is probable to cost, throwing away the lives & money spent to get us to this point, or we can, yanno, finish the damned job, continue to push to victory for our side with all the positives that holds for the future.
I repeat: We are there now. We are winning. We can win, or we can lose. Since you seem to want us to lose, why?
If you don't want to lose, then what exactly is your solution?
Like it or not, the problem does in fact exist and it does need a solution.
