Appeal, why do we need to appeal to him, just use the proper diplomatic processes with Iran. What do you think a bomb dropped in his backyard by one of our planes will change the way he and some of the people in power think.....nope. I hate repeating myself, but no matter how backward and wrong, or how tough they act, they still will use common sense. Seeking to effect another one is more the fear propaganda.
So when Ahmadinejad continues to advance his nuclear program (against UN warnings) and publicly states on a number of occasions that Israel should be wiped away, we should just let them be, because "they will still use common sense"? How does the term "common sense" at all apply to a man who denies the Holocaust and calls Jews "pigs"?
And if we do strike Iran in August, it won't be the first hit. It will be backing up Israeli forces, which absolutely will not allow Iran to have The Bomb.
I'm more worried about Iran developing The Bomb and selling the technology to terrorist groups (al-Qaeda, Hezbollah) than The Bomb actually being used by the Iranian military. We can not allow that to happen. If we allow Iran to continue to their own devices unchecked, we will be allowing a Nuclear Holocaust to occur. Such will be the case, unless someone prevents that from happening. There are 2 countries in the world willing to step in and accept that role: Us and Israel.
You think the US should not "police the world." I shudder to think where this world would be without the military might of the US. Without the US, Hitler and Tojo would not have been stopped. North Korea and Libya would still be developing nuclear technology. Saddam Hussein would still be in power. The list goes on and on and on.
