Iran

I am not 100% what should be done about Iran - here is one view I found...
Do read the whole, rather long, article but here is the ending:

"For Bush is right about the resemblance between 2008 and 1938. In 1938, as Winston Churchill later said, Hitler could still have been stopped at a relatively low price and many millions of lives could have been saved if England and France had not deceived themselves about the realities of their situation. Mutatis mutandis, it is the same in 2008, when Iran can still be stopped from getting the bomb and even more millions of lives can be saved—but only provided that we summon up the courage to see what is staring us in the face and then act on what we see.

Unless we do, the forces that are blindly working to ensure that Iran will get the bomb are likely to prevail even against the clear-sighted determination of George W. Bush, just as the forces of appeasement did against Churchill in 1938. In which case, we had all better pray that there will be enough time for the next President to discharge the responsibility that Bush will have been forced to pass on, and that this successor will also have the clarity and the courage to discharge it. If not—God help us all—the stage will have been set for the outbreak of a nuclear war that will become as inescapable then as it is avoidable now."
