But that is the nature of intelligence. No country has perfect intelligence. Short of having a spy in every governmental agency of every country and every terrorist organization on earth, intelligence will always be incomplete, imperfect, etc. However, at some point you have to put two and two together assuming it will be four, but sometimes it comes up three.
Hussein admitted to possessing specific amounts of specific BW and CW agents after the Gulf War; our inspection teams went in and discovered less than he claimed and destroyed what they found. That left the unaccounted for portion remaining somewhere. We can't assume that Hussein destroyed them and didn't tell us for no reason.
We also gather intelligence through satellite imagery, but without HUMINT to further explain what we're seeing, we can only safely assume that facilities once used for WMD production then shut down after the Gulf War, but then reactivated for undisclosed reasons, are being used for WMD production.
We can also only safely assume that the Hussein regime's kicking out of U.N. inspectors in '98, coupled with the cat-and-mouse games it was playing in late-2002, was done to conceal things they didn't want us to know. There is no other plausible reason.
Put that together with intelligence that we receive from the Brits, French, Russians, Israelis, Germans, Italians, etc., Bush made the correct decision. Intelligence will never be perfect because it is the product of humans, but we need to have a leader who is willing to put his political future on the line in order to protect this country, and ultimately, the world.
As I said on another thread this morning, the Frank Church/Jimmy Carter politicians that gut the Intelligence Community's budget and put unrealistic restraints on its sources and methods, coupled with the Oprahized public that winces at the thought of ethnically profiling young Arab males taking flying lessons, are what needs to be negated or reformed in order to make our intelligence capabilities better.
