Would a bigger U.S. Army have stopped 9/11?

The Pentagon has presented plans to cut $487 billion in defense spending in the next ten years. It's not much but it's a start. It proposes to shrink U.S. ground forces with 100.000, slow the purchase of next-generation aeroplanes and retire old planes and ships.

This is the response of Republican Senator and defense expert John Cornyn:

"Taking us back to a pre-9/11 military force structure places our country in grave danger," said Sen. John Cornyn, R-Texas, a member of the Senate Armed Services Committee.

So would, according to this Republican, 9/11 not have happened if the U.S. would have had three more infantry divisions? Or one more aircraft carrier?
Isn't it amazing that the American public keeps voting these nitwits in power? The only thing that could have stopped 9-11 was President George W. Bush listening to Clinton experts like Dick Clarke and not ignore reports like, "Bin Ladin Determined To Strike in U.S."
