WASHINGTON, Dec. 18 (Xinhua) -- U.S. President Donald Trump on Monday announced the national security strategy, the first of its kind since he took office in January and the 17th since the former Reagan administration began to submit the report to the U.S. Congress in 1987.

According to the security strategy which was released by the White House, Trump said the strategy, "builds on the 11 months of Presidential action" that features "principled realism," identifies four vital national interests or "four pillars," namely, to protect the homeland and its people, promote the U.S. prosperity, preserve peace through strength and advance the U.S. influence.

According to Michael O'Hanlon, a senior fellow on foreign policy at the Brookings Institution, Trump's upcoming report shows "there is a sense among some of the top team" in the White House that other nations are taking advantage of the United States.
