Answer
Answer:
It created the Department of Homeland Security to prevent terrorist attacks.
Brief Explanations:
After 9/11, the US formed the Department of Homeland Security to enhance security and counter - terrorism efforts. The other options are incorrect as there was no draft to significantly increase military size, the CIA was already established before 9/11, and the FBI was not replaced by the US Army.
