Truman stated:<\/p>\n\n\n\n<p><em>\u201cI believe that it must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures.

Based on the Truman Doctrine and American containment, the theory held the idea that if Soviet communism was able to spread into a single country, then it had the potential to spread to all of the other surrounding countries.\u00a0 The basic idea was that the American&#8217;s needed to prevent the first domino from falling (country turning to communism) in order to prevent the spread of communism.\u00a0 American containment was based on stopping communism any place it spread to, and as such, the domino theory helped explain the perceived need for the United States&#8217; involvement in international issues.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"540\" src=\"https:\/\/crunchlearning.com\/website_ec2cbfb0\/wp-content\/uploads\/2026\/03\/Domino-Theory-in-the-Cold-War-Infographic.jpg\" alt=\"Domino Theory in the Cold War Infographic\" class=\"wp-image-6184\" style=\"width:800px;height:auto\" srcset=\"https:\/\/crunchlearning.com\/website_ec2cbfb0\/wp-content\/uploads\/2026\/03\/Domino-Theory-in-the-Cold-War-Infographic.jpg 720w, https:\/\/crunchlearning.com\/website_ec2cbfb0\/wp-content\/uploads\/2026\/03\/Domino-Theory-in-the-Cold-War-Infographic-300x225.jpg 300w\" sizes=\"(max-width: 720px) 100vw, 720px\" \/><figcaption class=\"wp-element-caption\">Domino Theory in the Cold War Infographic by History Crunch<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Containment in the Cold War was a foreign policy that was used by the United States as a means of preventing the spread of communism and Soviet expansionism.
