After the attacks on september 11, 2001, how did u. s. foreign policy change?

Probably the most noticeable thing that happened after the 9/11 attacks were the amount of intervention we had with enemy countries that posed a threat to the US. During this time the word "terrorism" was first really established to explain the acts of the enemy.  There was also a lot of defensive spending to protect the homefront to prevent another 9/11 from happening.

On april 20, 1814, the dethroned emperor left france for the isle of  elba, where he was exiled under the terms of the treaty of fontainebleau.napoleon  would be allowed to ruleelba, which had 12,000 inhabitants. perhaps cruelly, the treaty allowed him to retain the title "emperor."
