At a Glance: US National Security Strategy by VOA News President Donald Trump Monday unveiled his national security strategy, a blueprint for future military and foreign policy, defense spending, trade negotiations and international cooperation. The security strategy is built around four pillars: 1. Protecting the homeland * Reforming the immigration system and strengthening border control * Targeting transnational terrorist groups and crime syndicates at the source * Keeping critical infrastructure and digital networks safe * Deploying a missile defense system 2. Promoting prosperity * Retaliation against "economic aggression" * Embracing "energy dominance" by removing obstacles to exploitation of shale and other domestic resources * Making America more than self-sufficient in energy, including development of nuclear and other power sources * Fighting theft of American intellectual property 3. Peace through strength * Rebuild America's military strength * Getting American allies to spend more on defense * Ensure the balance of power remains in America's favor in key regions -- the Indo-Pacific, Europe, and the Middle East 4. Advancing American influence * Diplomatic and development efforts will focus on protecting U.S. interests, finding economic opportunities for Americans, and challenging competitors * Promote free market economies, private sector growth, political stability, and peace * Shift away from a reliance on assistance based on grants to approaches that attract private capital
