Support for Iraq - then vs now

I'm a conservative and I have some concerns about the way the president is handling Iraq. I'm not going to support him just because he is a Republican president - I'm going to support him as long as he does the right thing. At the start of the war I thought that deposing Hussein was a good thing because he was a ruthless dictator who was reponsible for killing thousands of his own citizens. As ugly of a situation as it was only America and Britain had the guts to stand up to him. Now that we've been in the war for some time I've changed my position because it seems that the opportunity that we've given the Iraqi's has been met with thankless anger and I don't think that the whole issue is worth any more American lives. I certainly wouldn't want my son there fighting and risking his life. FYI, I served in the Seabee's for 6 years. I support our military. I just don't want any more of them to have to give up their precious lives for an ungrateful nation. Not once have I heard anyone with authority there thank us for our sacrifices and that truly disgusts me. I say - lets find a way out of there as quickly as possible.
