President Trump vowed on Tuesday to prevent a “beachhead of terrorism” from forming in the U.S., and promised to “demolish and destroy” the Islamic State.

“We have seen the attacks in France, in Belgium, in Germany and all over the world,” Trump said during his first speech to a joint session of Congress. “It is not compassionate, but reckless, to allow uncontrolled entry from places where proper vetting cannot occur. Those given the high honor of admission to the United States should support this country and love its people and its values.”
