It is not unreasonable to question the wisdom of our decision to invade Iraq. Hussein, evil as he was, held Iran in check and did not in fact support terrorism other than his own. It is unfortunate that we were misled by faulty intelligence. Perhaps our efforts in Afghanistan would have been enough to occupy Al Qaeda's attention.
Sunday morning I saw a former Muslim speaking about the motives of the Islamic jihadists. I gleaned this: The jihadists decided to draw the Soviet Union into Afghanistan, and they feel they caused the collapse of the Soviet Union. Now we're in their sights. Not because of our involvement in the Middle East, but because we are an ideological enemy of the establishment of a regional or eventual world-wide Caliphate.
The 9/11 attacks were meant to draw us overseas. But if we'd left well enough alone, they just would have done something else to provoke us. I understand the position of some Democrats and many Libertarians that this is an illegal war. Actually it's unconstitutional at best, and our Constitution was derailed by the development of "constitutional law" in the early 19th century, effectively giving courts supremacy over the legislative and executive branches. President Bush did nothing wrong according to current application, otherwise the Dems would have his hide nailed to the wall.
