Attention UN moron... there will be no 'smoking gun'... only a mushroom cloud, most likely over Tel Aviv, Washington DC, and/or NYC.
We'll be at war at the time of our choosing, and it will be their fault.
Self-Defense is a valid and legimate reason for going to war.
Your point raises an interesting question. Given Israeli intelligence and given their past history with Saddam and anything nuclear, don't you think that Sharon would immediately dispatch any A-bomb building effort by Iraq as they did in 1981? The Arab world would fume and rant, but as in 1981, they would do nothing in terms of launching against Israel.
Israel is always our canary in the coal mine.
