Discuss the potential risks posed by both citizens and immigrants in regard to terrorist attacks, and the perspectives surrounding immigration policies that allow for mass migration.
Clearly there are "terrorists" in our country who are citizens. What you seem to actively ignore is that there are also possible immigrants for other countries who want to come to the US to attack us. There are many incidents over the past year, both here and in Europe, committed by immigrants. Even Angela Merkel, who supported mass immigration into Germany, now regrets her actions. You may also be a "poor fool".
