Answer:
Containment.
Explanation:
The policy of containment is a foreign policy proposed by the government under the Presidency of Harry S. Truman to limit the powers of the Soviet Union and its spread of communism after World War II in 1947. This policy was a reply to the Soviet Union when it started to expand its communist control in Eastern Europe and Asia. The idea of containment policy was to make countries well-off enough to avoid the lure of the Soviet Union. It provided support for countries that rejected communism. Americans fought on the sides of the nationalists to try to stop the spread of communists.
The '' 'Zimmermann Telegram' '' was a telegram sent by Arthur Zimmermann, Minister of Foreign Affairs of the German Empire, on January 16, 1917 (during the First World War), to the ambassador of the land of clubs, the Count Heinrich von Eckardt. In it, the ambassador was instructed to propose a proposal for Mexico to betray the United States. It was intercepted by the British, and his made the United States go to war and eat the tail of the Germans.
The initial message included proposals for an affair between Mexico and the German Empire, while the latter would still try to remain silent with the United States. In the event that this policy screwed up, the diplomatic note suggested that Mexico should date the German Empire and launch a military attack against the United States.
