We're there. So stop saying 'bring the troops home' people, because if we do that without winning, all those soldiers who have died fighting will have died in vain. Then it will truly have become a worthless war.
Like it or not, agree with it or not, WE ARE THERE. And if our troops are there, we need to support them regardless of our support for the war or not. They haven't chosen to be there, it isn't their fault. So all we can do is keep them in our thoughts, and hope that they stay safe, win the war, and come home when they have.
