Answer:
Speaker 2: The United States has an obligation to protect its allies from invasions.
Explanation:
In 1949, after the end of WW2, the United States formed an Alliance with its allies, pledging to defend each other under attack and to safeguard mutual freedom and safety.
This alliance came to be known as the North Atlantic Treaty Organization involving the United States, Canada, and 10 Western Europe, Democratic Nations.
The reasoning as to why the other choices are incorrect goes as follows:
Speaker 1 would not agree because by forming NATO, the US is essentially agreeing to be involved in foreign affairs under attack, and NATO's goals at the time included preventing the spread of Communism.
Speaker 2 would agree- in joining NATO, the US is promising to protect its allies from invasion.
Speaker 3 would not agree because NATO countries are all democratic. The communist states would form their own pact in 1955 known as the Warsaw Pact.
Speaker 4 would not agree, as the Soviet was a huge actor at the time, and America's reason for joining was mainly to prevent the spread of Soviet ideologies and to protect itself and Western Europe against potential Soviet attacks.
