It would seem um,...uneconomical, to *waste* that many terrorists, but then, they do have them to spare. Suicide bombers don't always get a better kill rate, so it is a possibility.
However, if their aim to spread terror, while it may work in some locales, it has too much potential to backfire. US citizens are not EU pantywaists. They will not put up with it for long and people will carry into gun free zones if they feel it necessary.
Allowing an armed citizenry can work just like it does in Switzerland.
