re: Afghanistan
Geoff: "So invade a country over one guy?"
My Reply: Well, since this "one guy" was responsible for the murder of nearly 3,000 Americans and was no doubt planning the demise of more under the protective eye of the Taliban, yes, absolutely. Apparently you don't think so.
You are failing to connect the dots. The invasion of Afghanistan was justified by the deliberate attack on Americans on American soil. That's a clear cause for war. Meanwhile, the invasion of Iraq was "justified" by the false assertion that Saddam had chemical and biologicial weapons that did not actually exist. That's not.
