Pre-9/11- did not do his homework, and take urgent pleas seriously. he could have done a bit more it may hve helped
On 9/11- did not act like a leader. Was confused, shell shocked in a classroom, instead of immediately addressing etc. Popped up at different locations with poorly written speeches.
Post 9/11- did not listen to advice of both consvervative and liberal legal advice as to how to handle dealing with Al Qaeda in an effective manner.
Was totally over run by the V.P. and Neo-conseravative ideologues that saw 9/11 as their ideal laboratory to test their ideas of Democracy through force- eventually invade Iraq in order to spread democracy

Post9/11- Squandered the compassion of a very sympathetic world, spat in their face and said we will do things OUR way. Probably his biggest mistake of all- a war on terror would require the collective ideas of all of our close allies. Therefore "go it alone" was just plain stupid and impulsive.

He ended up with the following allies: Britain (but not the people), Vanuatu, Georgia, Romania, Poland.... hmmm
Completely bungled capturing the highest value Al Qaeda cadres, took recources away, and shifted focus on Iraq
Went to Iraq, despite overwelming intelligence pointing out that this would be a very very risky move.
Went anyway, and had no preparations for post-war, or marshall law, or counterinsurgency. Surge FINALLY was adopted, but after country was ruined by civil war. He was advised over and over to go with 3-400,000 troops.
Again, he could not assert himself and Rumsfeld walked all over him.

Fieth, Woo, Cheney and other sinister characters appealed to Bush's cruel (134 deathpen cases in Texas) side in order to extract information. Instead of listening to those with years of interrogation experience he prefered to "take the gloves off" too prove a point instead of winning a war of ideologies. Because of Torture, Extraordinary Rendition, and the imprisonment of 1000s of innocent villagers subjected to the worst aspects of American culture- heavy metal, sleazy sex, humiliation- America lost its moral compass in the eyes of other countries. This is the America that organized and held together the Nuremburg Trials. Nazis, accused of far worse crimes than blowing up planes - such as the death of 30,million plus civilians, cutting out peices of brains of twins to see what would happen, forcing sex changes to see what would happen, gassing Jews as a Final Solution etc. One of the greatest defeats, and battles won during WWII was the right of the accused war criminals to face their accusers. Somehow we find that a motley group of somewhat half assed Arab terrorists merit far greater measures???WTF?

So, with no clout, no economic or energy visions, no moral authority, no authority whatsoever -here is what the next president will have to fix:

Dealing with a now Powerful Russia. Powerful Iran. American ridiculed by such people as (and this is embarrassing) President Chavez.... Basically, no one had any respect for him. Putin took him for a ride ("I saw his soul") KGB agents dont have souls...

People may not have liked Truman, or Lincoln, or Nixon for that matter, but they all had at least some degree of respect- even Nixon. Despite Watergate, many admire Nixon despite his being a bit crazy. Bush has none. No Respect, not a good prospect for historical significance.
