No I don't like Saddam. No I don't like Bin Laden. Does this mean I want to drop a nuke on their country? Sure it would get rid of these guys, but at what cost. You see that is the question. What cost and with what effectiveness? You might say, "Well we didn't nuke them, what's this guy talking about?" And your right we didn't, you'll also note that they are both still alive, still killing, and in my opinion still very great threats. Now yes they are in hiding and no they don't have countries of their very own any more, but they don't need them. Saddam is perfectly happy in the roll of a Baghdad gangster picking off his adversaries and waging a political war. Why shouldn't he be, that's who he was before we basically put him in power. Bin Laden was given quite the run around I'm sure, but it's nothing he hasn't been doing most of his life. And for every terrorist camp bombed 10 will spring up in other countries full of people willing to fight the foreign infidels. Every hostile act we perform adds fuel to the fire that gives Bin Laden his recruits and support. If we were to stop giving Bin laden martyrs what would he bomb us with?
To me, Bin Laden is the embodiment of social angst. We may never capture him, hell he may already be dead. You see, it doesn't matter. He will always exist as long as we provide a reason for him to.
In Saddam's case I disagree with the politics of it all. The man could have been contained without war. He could have been stopped without firing a bullet. Saddam isn't the whole problem that country has either. Iraq has an enormous history of bloodshed between ethnic and political groups. Most of the complaints you have about Saddam's cruelty isn't going to go away with Saddam. It may go behind closed doors, but there will continue to be victims every day of a battle that began there millennia before we ever existed. This has no short solution, though I wish it did.
Look, I'm human too. I hate death, suffering, and people who enjoy bringing it about, but open your mind a bit. This isn't a Hollywood movie, there is no single bad guy to kill and there is no girl in distress to save. What we do have, is our hands stuck in a jar full of 1000's of years of conflict, wars, and hate for foreign conquerors. Let's learn from the history in this place, conquering and warring in the Arab lands has never yielded peace. The only peace that has ever existed in that region has come through cautious respect building and trade.
