It seems Trump wants to curb immigration to the USA from certain Muslim countries in the Middle East. 

When Muslims must follow Islam and the verses in the Qur'an, the holy book of the religion Islam, and when many verses in the Qur'an call for jihad (struggle) and when about 100 verses in the Qur'an call for the destruction of Jews, Christians and non believers, maybe it's a good idea not to allow Muslims into the U.SA. from countries where radicals faithfully follow Islam and the verses in the Qur'an and when one can't distinguish moderate Muslims from radicals. 

Maybe, the U.S.A. and other western countries should think about allowing Muslims into their countries only after Muslims have renounced the verses in the Qur'an that call for jihad (struggle) and have renounced the verses in the Qur'an call for the destruction of Jews, Christians and non believers. 

Would that work?  Could we believe them?
