It’s hard to find anything George W. Bush did that was a positive contribution that left a positive legacy. It goes the other way. From Andrew Napolitano at lewrockwell.com:
In the days and months following the attacks of 9/11, the government laid the blame for orchestrating the attacks on Osama bin Ladin. Then, after bin Ladin was murdered in his home in Pakistan in 2011, the government decided that the true mastermind of 9/11 was Khalid Shaikh Mohammed.
By the time of bin Ladin’s death, Mohammed had already been tortured by CIA agents for two years in Pakistan and charged with conspiracy to commit mass murder, to be tried before an American military tribunal at Guantanamo Bay, Cuba.
Throughout the entire existence of the U.S. military detention camp at Gitmo, no one has been tried for causing or carrying out the crimes of 9/11. The government only tried one person for crimes related to 9/11. That was Zacharias Moussaoui who pleaded guilty in federal court in Virginia to being the 20th hijacker and then was tried in a penalty phase trial where the issue was life in prison or death. The government spent millions in its death penalty case, which it lost. A civilian jury sentenced Moussaoui, who never harmed a hair on the head of anyone, to life in prison.
Mohammed, meanwhile, and four other alleged conspirators, have been awaiting trial since their arrivals at Gitmo in 2006. Since then, numerous government military and civilian prosecutors, as well as numerous military judges, have rotated into and out of the case.
The concept of military tribunals was born in the administration of President George W. Bush, who argued that 9/11, though conducted by civilians, was an attack of military magnitude and thus warranted a military response. This pathetic knee-jerk argument, of course, not only brought us the fruitless and destructive wars in Afghanistan and Iraq; it also brought a host of legal problems unforeseen by Bush and his revenge-over-justice thirsty colleagues.
