Gee, why would the government of any country in the world want to take the chance of allowing Islamic, radical, terrorists into their country?

And, why shouldn't the U.S. government be able to pick and choose the people it wants to come to the U.S.A.? 

And, as I have asked before, why don't more Muslim countries take more of the refugees from Muslim countries? 

And, why don't countries like Russia, China, Japan, Australia, South Korea, etc. or countries in South America take more refugees from Muslim countries? 

Why should the onus be on America to take a chance?
