If you REALLY understand how the Arab-Islamic mind works, that is, if you understand how the ENEMY thinks then the only way to deter these heinous crimes is thus:
1) EVERY single terrorist must die, on site.
2) EVERY terrorist house must be blow up and not in a controlled explosion but one that creates collateral damage to the terrorists neighbors homes as well.
3) The main family of the terrorist must be expelled to Gaza or out to sea.
The Arab terrorists know that they might die as a “Shaheed” or martyr and their family honored but if they knew their families will suffer, they MIGHT think twice.
The reason for this approach is based on the fact that in the Arab-Paleostinian mentality, destroying the home is but a physical structure that can be rebuilt but if you remove the family from their home it causes pain but not nearly the pain inflicted on the Jewish family that had their relatives butchered at the Friday night Sabbath table...
The policies you suggest will be the real policy when an elderly Lindsay Lohan Tweets, “All Muslims must die, ##Killthemall.” And, when the mainstream press, whatever that means at the time, has talking heads demanding the government kill terrorists.
I say, give it fifty years. Probably not a moment sooner. And, yes, by that time the western world will barely be recognizable from our perspectives.
