Step-by-step explanation:
This quote strengthens the thesis that the Cold War conflict was about the Soviet Union wanting to expand power and influence through spreading communism. The quote suggests that if Greece falls under the control of an armed minority, the effect on Turkey and the Middle East would be immediate and severe. This implies that the Soviet Union's influence could potentially spread throughout the Middle East if they were successful in their attempts to spread communism. The quote also suggests that if the West fails to aid Greece and Turkey in this fateful hour, the consequences will be far-reaching, which highlights the importance of containing the Soviet Union's expansionist ambitions. Overall, the quote supports the idea that the Cold War was primarily about the competition between the Soviet Union and the West for power and influence.
