Just before meeting with Bill de Blasio (who recently chose a terrorist to lead a parade), Khan stated that:

"Terror attacks are part and parcel of living in a big city."

At no time has Khan ever even mildly criticized rabid Islamic radicals or those who practice Sharia Law.

Khan's policy is one of reaction, not a pro-active approach which would close radical mosques, deport extremists, strip the passports from those who fight for Daesh, and clearly state that those who practice Sharia Law will not be allowed entry to Britain.

Trump's policy, by contrast, is pro-active,  but it verges on a counter-productive intolerance which will understandably alienate moderate Muslims as well as all reasonable persons of other beliefs.

What must be done is separate the wheat from the chaff: the terrorist Muslims from the good Muslims.

Neither Khan's complacency nor Trump's perceived intolerance is good policy.

What's called for is a realistic prevention of Islamic terrorism.
