Bush says not to blame past government agency errors that failed to prevent 9/11. No, we just need a new agency! With lots of money!
Of course, growing the government will not solve anything. More security at airports = long waits and crowded security lines = perfect terrorist target. So, we have to check everyone entering the airport = long lines to get into the airport itself = perfect terrorist target.
The only way to stop terrorism is end a foreign policy whose unintended consequences are the opposite of our goals and whose primary result is to oppress people who then want to blow us up.
