Radicalization of US-born or US-admitted Muslims by clerics, relatives, social media -- is real, eg [1] (Fort-hood terrorist), San-Bernardino terrorists [2].
Therefore, the argument could not just be about questioning if any visa/green card holder for the initial list of 7 'banned-county -->to--> Muslim terrorist perpetrating killing on US soil'.
It is a preventive measure, with a time limit . Very appropriate for this period of time, given the war with ISIS.
I am not, however, impressed with the execution or the preparation that went into this particular order. I would like to see a different level of scrutiny and reduced personal inconvenience afforded to US green card holders.
Appreciate that majority on this forum, including highly respected scientists, will disagree with me. But please allow the expression of, at-least partially informed dissent.
