President Trump’s very public oval office push to secure $5 billion in funds for the border wall—and the Democratic leaders’ public refusal to go along with the idea—leaves many wondering if we might see an end of the year government shutdown over mass, illegal uncontrolled immigration.
But if President Trump is successful in securing the $5 billion in funding for the wall and the wall is built, will it actually work to deter illegal immigration? The answer is an unambiguous Yes! If there’s any doubt, one need look no further than the San Diego sector of the U.S.–Mexico border.
