Although the Cold War is over, the Truman Doctrine has left a legacy on the foreign policy of the United States that still exists to this day. While the Truman Doctrine was focused on preventing the spread of communism, today's foreign policy applies aspects of it to prevent the spread of radicalized terrorism and promote democratic movements around the world.

A central idea of the Truman Doctrine is that the United States can protect its interests by supporting stability abroad. It recognizes that the world is an interconnected place. Ensuring localized stability in one place has reverberations around the world. To that end, much of US foreign policy centers around maintaining stability in places where instability could become an issue. Much of this is done with the purpose of preventing localized radicalization that could develop into globalized terrorism.

Furthermore, the Truman Doctrine promoted the idea that the United States could be the leader of a global community. During the Cold War, the country rallied numerous allies to its side and formed a broad coalition. While this role has been diminished in recent years, much of the United States' foreign policy is still centered around the notion that the country is a leader in safeguarding democracy around the world. Other nations hoping to promote peace and freedom still look to the United States as an important ally.
