How can Trump deny Syrian refugees?

Donald J. Trump expressed appropriate outrage over the Syrian government’s use of chemical weapons against civilians — including children.

The president is right. Syrian dictator Bashar al Assad has committed war crimes and crimes against humanity. And I do support the decision to launch Tomahawk cruise missiles at military bases believed to be where the Syrians launched the chemical weapons against their fellow citizens.

However …

How does the president justify his decision to ban refugees fleeing the civil war in Syria because they happen to originate from a Muslim-majority nation?

His statement condemning the casualties inflicted on children seems to fly directly against his heartless decision to ban refugees.

How do you balance one against the other, Mr. President?
