Well, it's somewhat debatable that we're much safer because we invaded Iraq.
But I've got no qualms at all about giving a big thank you to our troops for sacrificing so much in service of our country. Whether the policies are right or wrong, these people go out and do their best to enforce the will of our democratic republic. We'd be completely fucked with out them, and I hope we do a better job of both using their service and rewarding their service in the future.
