As I see it, there are (2) points to Harley's thread.

1. The decision to go to war was not well thought out.

2. Once we committed ourselves, we clung to the neocon plan of a limited number of troups and supplies, which were significantly less than what the generals or "experts requested."

It's not a question of half full, half empty. It's a question of whether our leadership is nimble and confident in its ability to make changes, when they are needed, in lieu of sticking to a plan out of errogance because they're affraid to be second guesed.
