Answer:
Korea and Indochina were two regions that the Eisenhower administration used Brinkmanship Effectively.
Explanation:
First of all, Brinkmanship is the act of taking advantage of a situation of possible conflict by carrying on different strategic movements suggesting an imminent act of war without executing it. For example, Russia surrounding its border with nuclear incredibly fast missiles. Or the NATO establishing bases around the Russian border to prevent an outbreak.
Second, the cold war sides were the western and eastern blocks. Russia and Poland were active western block members of the Eastern bloc that was composed by The U.S. under Eisenhower administration. However, some countries weren't part of the block but that the Eisenhower administration skipped confrontation by performing brinkmanship. Korea, Vietnam, Indochina, and Cuba were a few of them. But, the Eisenhower administration only used brinksmanship against Korea and Indochina, because they confronted them indirectly during the Eisenhower administration.
