Saddam murdered millions of Iraqis. Doesn't mean it was a good thing to get involved and remove him for whatever reasons that were given to the American people. I was 18 years old in 2003 and a supporter of the Iraq War. Hindsight tells me I was dead wrong. If Egypt, Libya, Syria or any other country wants to overthrow their dictator, that's fine by me if it means we don't get involved unless it's absolutely necessary. No need to get involved and get our hands dirty.
Also these dictators may be horrible people but let's not think that among these rebels, there isn't one to replace them. I know it's kind of lame but there is that quote from The Patriot. "Why should we trade one tyrant 3,000 miles away for 3,000 tyrants one mile away."
