In a Dec. 17 article, the Washington Post pointed out that President Donald Trump reneged on his border-wall promises ("What is Donald Trump's border wall really for?"). His plan now cuts the wall by more than half, and much of what has been done has only been the maintenance of barriers that stop or slow the entries of cars and trucks, not people.

The piece pointed out an important item Trump neglects: that huge numbers, "two-thirds," arrive by legal visas and choose to stay as illegals.

The piece, however, did not mention that walls work. Israel built a 440-mile wall that stopped all uninvited guests. It worked so well another 100 or more miles of wall is being added. Remember the Great Wall of China? For centuries, it stopped or slowed invaders intending on changing China’s society and religion. There are lots of examples that walls work.

In addition to a wall, the U.S. should limit total immigration to no more than 200,000 per year, take the steps necessary to prevent illegal border crossings, prevent visa overstaying, set up a comprehensive monitoring system, make E-Verify mandatory for all U.S. employers, fine employers who hire illegal immigrants, eliminate federal money for colleges that admit illegal immigrants, enforce laws against state and city sanctuary practices, end chain migration, end birthright citizenship, end the catch and release of illegal immigrants, deny visas to nations that refuse to repatriate citizens, and require asylum-seekers to apply in their own country with the agreement that it's only a temporary status of no more than a few months.

Looking at the list above, we can better understand why there are so many illegal immigrants in the U.S. — with more coming. Law enforcement is broken. Desperately needed policies are ignored.
