Editing Reagan Doctrine (section)

==Background==
The Reagan Doctrine followed in the tradition of U.S. presidents developing foreign policy "doctrines", which were designed to reflect challenges facing international relations, and to propose foreign policy solutions. The practice began with the [[Monroe Doctrine]] in 1823, and continued with the [[Roosevelt Corollary]], sometimes called the Roosevelt Doctrine, introduced by President [[Theodore Roosevelt]] in 1904.

The post–[[World War II]] tradition of presidential doctrines started with the [[Truman Doctrine]] in 1947, under which the U.S. provided support to the governments of [[Kingdom of Greece|Greece]] and [[Turkey]] as part of a Cold War strategy to keep both nations out of the Soviet sphere of influence. It was followed by the [[Eisenhower Doctrine]], the [[Kennedy Doctrine]], the [[Johnson Doctrine]], the [[Nixon Doctrine]], and the [[Carter Doctrine]], all of which defined the foreign policy approaches of these respective U.S. presidents on some of the largest global challenges of their presidencies.
