Good article Cath. It gives a detailed look at how little Bush did to prevent the attacks of 911, and shows how Clinton had a plan in place, The same ideas as was finally implemented by George2, but unlike G1, didn't saddle G2 with a problem like Somalia.
It has been clear for the last five years that the Bush administration did little or nothing about the issue of terrorism. It failed to prevent a catastrophic attack, and then turned around and used that attack to justify an extreme foreign policy agenda that has left us in a quagmire in Iraq and Afghanistan and has weakened our position in the world.
That seems to sum up the legacy of the Bush presidency.
