I feel safer knowing my military is kept in reserve for a real threat. Also somewhat safer (or less apprehensive) keeping Iraq the way it is, rather than having it disintegrate into warring factions, some supported by Iran, possibly spreading fighting into Turkey. Finally, there's other sources for WMD's for terrorists, for example if they have money they can buy them from North Korea. We certainly can't afford to attack every country that could possibly supply WMD's to terrorists.
And Saddam (who you agree has WMDs) is not a "real threat" because.....

Yes, that is also a problem.

Probably not, at least not all at the same time. This is not an argument for attacking none of them, though. One thing at a time.
