<h2>Answer: Dwight D. Eisenhower
</h2>
Eisenhower was a General of the Army of the United States, who during the Second World War, was the supreme allied commander in the western front of Europe and directed the battle of Normandy.
This military operation was initiated on June 6th, 1944 with the invasion of Normandy by the Allies during the Second World War and culminated in the liberation of the Western Europe territories occupied by the Nazi Germany.
In addition, Eisenhower was the 34th president of the United States between 1953 and 1961.
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.
