Charles Sumner was a radical Republican in the sense they wished to destroy all remnants of the Confederacy and give African Americans full rights as citizens. So he wanted a "guarantee that former slaves
<span> would have equality with whites.</span>"
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.
