They weren't just opposed to our military deployment to defend South Vietnam's sovereignty and liberty in that Southeast Asian war, which they disgracefully characterized as a civil war. They didn't just pooh pooh Communism's expressed desire for global domination. They were sympathetic to the Communists themselves and to the Communist cause, whether in the bowels of the Soviet Union, the jungles of Vietnam, or Nicaragua. Just look at how even today they romanticize Fidel Castro's wretched regime.
And now, they see America as on the wrong side (morally) of this war in Iraq -- as if we have invaded a sovereign nation and many of those fighting against us are morally justified in trying to prevent our "imperialism."
Regardless of their disagreement with our reasons for beginning the war in the first place, how can they fail to see clearly the demarcation of good and evil manifested in the terrorists' and "insurgents"' relentless barrages of mayhem and barbarism -- all to prevent the Iraqi people from self-rule and liberty?
All but the most muddleheaded among us has to understand that this war isn't between two opposing forces with arguably equal moral claims. As Tony Blair so poignantly stated, "Whatever people's feelings and beliefs about the removal of Saddam Hussein, and the wisdom of that, there surely is only one side to be on in what is now very clearly a battle between democracy and terror."
The Left can fool themselves all they want, but these international terrorists aren't going away. They are here to stay and wreak havoc throughout the world as long as they are able. We have no choice but to confront them now. If we don't, we will have to in much worse circumstances later, not because we attacked Iraq or have troops in Saudi Arabia, but because we represent everything that is repugnant to radical Islam merely by virtue of who and what we are.
