The invasion of Iraq was fully justified, morally, ethically, and legally. However, certain Muslim extremists have brainwashed a certain very small segment of our society to oppose the re-structuring of Iraq so that they can continue with their ridiculous Jihad against America.
Siding with that ridiculous Jihad is the surest possible guarantee that we will suffer even more violence that 9-11.
If we do not subdue these lunatics now, we will only make sure that we must re-do all the good we have done to date, and then, re-do it later at far greater cost in terms of life, limb, national prestige, and money.
In short, pacifists cause war. It is about all that they have ever done well.
