Listen to the leftists and liberals, and all you'll hear is how Iraqis hate us and kill our troops. Here's another truth, even more basic. The Iraqis are armed. We did not disarm the population. If Americans were the hated oppressors we're painted to be, we could NEVER get away with that.
Tyrants always disarm their people. The Soviets did, the Cubans, the Chinese, the Vietnamese, the North Koreans, the Nazis, the fascists, the Cambodians. They can't face an armed population. But Americans can and do in Iraq.
Perhaps that's why the leftists and liberals don't really want democracy in Iraq to succeed. They're afraid Americans will get a taste of it and remember what it was like to be a democratic Republic with all the intrinsic freedoms, including the right to bear arms and free speech.
