Bush was also a wimp when the aircraft was brought down over China. I am not “blaming” anyone for 9/11. There is plenty of evidence that was ignored, across many years.
But, Bush was the guy in charge. He has to accept responsibility because he was in charge. That is what leaders do.
He accepted responsibility and declared a state of war...half the country (Democrats and like minded malcontents) want to continue to consider terrorism a criminal matter...but like it or not we are at war with these people and it will be with us a long long time.
