Do you see any alternatives to close monitoring?

Simple, we just don't have the courage to do it:

(1) No Middle Eastern men are allowed to fly or work in or around airports.
(2) Do to Middle Eastern men what we did to the Japanese during WWII. Relocation camps.

If necessary, extend the above to all Islamic men. I guarantee that what I suggest above will only seem extreme until ten thousand Americans die in a horrible attack.

I agree about profiling Middle Eastern men (who form the majority of those who practice radical islam). But Islamists are recruiting non-Middle-Easterners, including black prison inmates and other ethnic minorities. I would include Middle Easterners among those to be profiled, but expand it to include any ethnicity practicing Islam.
