Most critical step is to be very stringent on which Muslims are admitted as legal immigrants or even on temporary visa’s. My understanding is Obama admin is admitting 300,000 Muslims on immigrant visa’s every year.
That kind of slop has to stop. There are a lot of practical, “religion-blind” things that could be done on that front. It’s because Obama is kissing up to the trouble-maker facet of the Islamic faith (”clock boy” is an excellent case in point) that we are having these problems now. Trump would be more like, I do not care if you are a Green Martian, there are certain criteria that must be met.
The best way to deal with the problem is to not allow Moslems into America!
