@JTT,
Pork and the largely unconstrained growth in the Federal government has been a concern in conservative circles since Washington's time. President Reagan's efforts to curtail the size of the central government was a welcome, if limited return to sanity. The cost of Star Wars technology was immense, but it was an important factor in ending the Cold War. Unfortunately, the Cold War merely increased the boldness of Radical Islam, and terrorist attacks on our cities at home and our interests abroad have been constant since.
The Shrub's response to 9/11 was appropriate and his Constitutional responsibility as Commander-in-Chief of the nation's military. The 9/11 attacks were by private citizens of several countries bound by radical religious zeal. So the National Command Authority had no clear national target to 'punish' for the attacks. Instead, the focus was upon those countries in Southeast Asia that openly supported and helped prepare Al Queda, or that had a long and continuing history of threats to regional stability by seeking weapons whose use is considered especially dangerous.
Saddam's Iraq was believed to be a special threat to the region, Saddam openly supported terrorism and terrorist groups, and his regime continued to oppress the Iraqi People. The Taliban made no secret of their support for Al Queda, and provided training and logistics for them. Iraq was geographically the easier place for our military to bring its forces to bear. Afghanistan, on the other hand is a logistical nightmare. Radical populations in Pakistan, Yeman, Syria and in various African nations stood by and applauded the attacks, but there was little evidence that their government approved. The Bush administration chose to resolve the Iraqi threat first, and failed to understand that building responsible governments is much tougher than smashing the military might of tinpot dictators. The fundamental correctness in the combined forces concepts was proven, but the administration's hope that transition to democracy would be fast and relatively easy was self-deception. We conservatives supported the President at the time, and I don't regret that now.
In hind-sight, Afghanistan was almost certainly more culpable than Iraq, but the political and geographic realities are also far more difficult to operate in. There are two keys that must be turned there. The first is Iran, and the second is Pakistan. President Obama is now at the helm, and we only hope that he will be able to make the tough choices that lie ahead in dealing with these two dangerous nations. This won't be easy, and one has doubts that President Obama is experienced enough and wise enough to handle the problems.
