The left has perhaps intimidated the Administration into taking a very cautious approach to Iran, Syria, the whole lot of them....The information we had on Saddam's WMDs was probably about as good as intelligence gets, and yet the media and the anti-war left has been shouting for a year and a half that the intelligence was "flawed." Personally, I would bet that the CIA's intel. on WMDs was pretty accurate, but that Saddam moved, hid, and destroyed this arsenal during the fog of war, and we cannot pick up the trail of where they went (even though there are persistent rumors and suspicions that much of the WMDs are in Syria and Lebanon). The CIA's reputation has been damaged, and Bush isn't about to rush into another war until the intelligence is pretty close to air-tight (which it may never be).
In the interest of winning the next election, the Democrats and their enablers in the news media have made it nearly politically impossible to protect this nation. Bush will do what he needs to do against Iran, but the task of protecting this country has been made more difficult with 16 months of naysaying.
