Maybe he left a future door open for case-by-case analysis of non-Muslim refugee claimants...
... as a balance to the Obama administration's policy that led to a headline of "Federal Judge Asks Why Obama Administration Isn’t Admitting Christian Syrian Refugees"...
... a topic I do not remember every reading about in the Globe and Mail?
From that article: "Ten percent of the Syrian population is Christian and “yet less than one-half of 1 percent of Syrian refugees admitted to the United States this year are Christian."
Given the much larger refugee numbers taken in under Obama, the new case-by-case Trump policy for Syria would probably have to run for decades before it could correct, on a per capita basis for Syrian refugees in recent history, for the massively pro-Muslim anti-non-Muslim approach reported during Obama's reign...
... well, reported in some venues, that is...

... by the way, where do I find your post condemning Obama for strongly favouring Syrian Muslims over Christians?
