Terrorism becomes a major concern of U.S. foreign policy.
This diagram is a timeline about foreign policy. The first box gives the Cold War as a priority when it comes to U.S. foreign policy. The second box for the terrorist attacks on September 11th. The last box must be what happened next. Options A and B should be eliminated because they happened before September 11, 2005. D is the best answer because after the terrorist attacks the U.S. declared a war on terror.
