When President Bush declared a “war on terror” after 9/11, how did this statement change US foreign policy?

For the first time, the United States would strike at terrorist groups, such as al-Qaeda.

The United States would no longer distinguish between terrorist groups, such as al-Qaeda, and the countries that harbored them.

The United States reserved the right to act in self-defense against terrorist groups.

The United States announced it would invade each member of the “axis of evil,” until they all gave up their WMDs.
