Heres a few reasons for terrorism
Israel has nukes they got them by us the United States
America supplies Israel with american made weapons which kill arabs
America occupied Islamic holy lands espically Saudi Arabia which pissed off Osama
Maybe terrorism is made up or over-exgrated to enfuel fear in ther American people. When the American public has fear they tend to vote for
conseveratives. So the consveratives give this fear to the Americans in order to have power.
