Answer:
United States and the Soviet Union.
Explanation:
The Soviet Union was trying to spread communism all over Korea. The United States joined in with South Korea to fight against the communist North Korea.
The attack affected the american security policies because after the attack the american security system was looked down on and also it was taken care of by making the security more stricter.It impacted the view of Islam because it was done by a Muslim group so Islam was looked at like a religion which allowed killing and brutal acts toward humanity.
I hope this helps and answered the second question based on how I think it is because I am a Muslim myself.
This is because both Puerto Rico and the Virgin Islands were unincorporated territories of the United States with the U.S president as head of State. There was no need to patrol Puerto Rico and the Virgin Islands as the U.S blockade was against Cuba, not against the two U.S territories.
