re: choices
1) Saddam had no more WMD's: it means we were mislead by the Administration, which is very damaging if it needs trust from abroad. (in the fight against terrorism, for instance).
2) Saddam smuggled the existing WMD's outside: it means waging war was the best way to loose control over them (looting, chaos all helped disorganize the country) and aggravate the problem..
Both scenarios feed the arguments of the anti-war folks.
