Yes that is exactly right this is ALL ABOUT IMMIGRATION now. This was a total failure of the immigration system. The borders need to be locked down, and everyone immigrating from known global terror hotspots needs triple scrutiny...
No other country in the world --- NONE--- would tolerate decades of infiltration by groups from countries KNOWN to be inimical to the host country.
Why should we spend wealth "triple-scrutinizing them?
Just keep all their asses out altogether!
Why were we educating those killers, anyway?
I agree with your suggested action but I am afraid/concerned that the cancer like cells of Islam have permeated already to the highest levels of government. A person only needs to see just a bit of the government personnel rosters to realize that the USA is infected. Take as an example how Norquist, who is married to an active Muslim, has take over the GOP organization and the elected sheep have taken this guy to be their shepherd. Of course when the shepherd gives the sheep food/money what is a sheep supposed to do—go baa baa.
