Dx, I agree with your assessment of Chavez, Ahmadinejad, and their ilk.
They really should not be allowed to draw even one more breath on this Earth.
The trouble is that Americans are so freedom-loving that we don’t want to assert our will on another people. I realize that this is not the view that most non-Americans hold of us Americans, but it is the simple truth.
So we always wait until creeps like these have lived FAR too long. We always wait until their insanity threatens to spill over into our own vital national interest, before we even begin to consider taking hostile actions against another sovereign nation.
