Okeydokey,
Lets rephrase that to say that Americans don't like to make the same mistakes twice, and won't continue with the same pattern that got them where they are today, and would be intollerant of an ongoing drawn out thing like say the IRA dispute...
And Nostradamus, EVERYSINGLE WEAPON USED ON SEPT 11 was completely legal to carry on any EU aircraft as well. Infact you could have BOUGHT them inside security at switzerland at the duty free shop or in London Heathrow at the Duty free shop.
What was exploited was not American security as no contraband was used in Sept 11. What was exploited was the same things things that you are argueing in favor of now! Complacency. "We don't need any extra measures." it worked up till now... It happend there but no, it couldn't happen here...
Cheers
Wino
