(post-9-11 era)

The post-9/11 era began after the terrorist attacks on the United States on September 11, 2001. This period brought big changes in global security, including the start of the U.S.-led “War on Terror” and military operations in Afghanistan and Iraq. Countries focused more on fighting terrorism by sharing intelligence, strengthening borders, and improving security measures. It was also a time when surveillance technology grew, and people debated the balance between safety and personal freedoms. These events greatly impacted world politics, economies, and how societies viewed security and terrorism.
