Answer:
There would be political unrest and an increase in the spread of communism.
Explanation:
The problems that could arise if the United States initiated the Marshall Plan in European countries without said countries’ cooperation is that "There would be political unrest and an increase in the spread of communism."
This is because, many of these countries would not accept the United States aids, and thereby further strain the level of trust among them. In turn, the Soviet Union would likely take advantage of the situation and ally with some of these European countries, thereby spreading communism.
