JAIME MCINTYRE: 5 things you should know about Trump’s new national security strategy.

Here are four:

What role does the strategy play in shaping policy? Think of the National Security Strategy as a mission statement, one that translates the president’s vision into a series of practical principles that serve as guide to policy decisions on everything from involvement in foreign wars to immigration law. In a recent speech, national security adviser Lt. Gen. H.R. McMaster called it “a dramatic rethinking of American foreign policy from previous decades.”

What are its guiding principles? The full strategy will be released Monday in conjunction with the president’s remarks, but McMaster has already sketched its four pillars in broad terms. They are: Protecting the homeland, advancing American prosperity, preserving peace through strength, and enhancing American influence.

Who wrote it? The NSS is largely a product of the National Security Council, including McMaster, his outgoing deputy Dina Powell, and Nadia Schadlow, a close confidant of McMaster. But the document was fashioned with input from experts inside and outside government, including members of Congress, think tanks, and industry CEOs.

How is it different? Under President Barack Obama, the U.S. focused on the “big 4 plus 1,” which is threats from China, Russia, North Korea, and Iran, plus terrorism. The Trump strategy also names China and Russia as “revisionist powers,” and North Korea and Iran as “rogue regimes.” But it also defines the threats in terms of economic competition, not just military strength.

Almost anything would be an improvement over prostrating ourselves in almost every way imaginable to protect and enrich Iran’s mullahs regime.
