If the U.S. government knew Israel had WMD in 1986 why didn't they attack Israel instead of Iraq during the?

So, the Jews killed JFK? WTF? You are insane. Also, because the leaders of Israel are not wackjob idiots bent on destroying the world, in spite of what racist liberals think. There are a number of countries that have nuclear weapons including Great Briton. The world does not want WMD's in the hands of dictators like Saddam
