President Trump yesterday reinstituted a travel ban he initially ordered early in his first term. It’s worth recalling why. 

One reason is that there is no way to vet people from many countries across the Middle East and Africa. As he noted in a seminal speech in Youngstown on August 15, 2016, admitting their citizens risks letting in adherents to the ideology of “radical Islam” known as Sharia, which requires its adherents to engage in jihad to impose Islam worldwide.

Sharia is the law of the land in most of the countries included in the new executive order. Recent terrorist attacks remind us that we must prevent more jihadists from coming here. They also underscore the necessity of removing Sharia-supremacists already here, in many cases illegally – and, as he promised in Youngstown, “stripping out” the networks that support them.
