Please look around you for a little perspective: America, including the trade towers mega act, has a history of far fewer threats carried out than nearly any other region. How about 10,000,000 Syrian survivors you spurn? How about Chicago's or Detroit's or DC's or Baltimore's or LA's annual domestically wrought death tolls? That constitutes "Problem" in the triage of issues confronting America. Terrorism continues to be largely in a threat- that is effectively paralyzing our country.
Trump uses an OLD schtick: "THE SKY IS FALLING (and only I can fix it)". That is why he "loves the America Worker"- we seem to eat it up and shit gold bullion. He IS the establishment- you think he cares about protecting you?
Let's get our children fed and educated, fix our paleolithic infrastructure, get healthcare put a dent in our crime and violence and draw down our debt! Let's leave the threat of terrorism in a slightly lower drawer. We are not a fearful nation.
