The United States helped overthrow Guatemalan President Guzman
in the early 1950s because he was suspected of being a communist sympathizer.
Following the end of World War II, the U.S was engaged in a Cold War with the
Soviets which was mainly an ideological war whereby the U.S aimed to stop the
spread of communism
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.
The battle of New Orleans. US victory I recommend looking into it. It's super interesting.<span />
