Nobody wants to be a victim of terror. But we must remember that no citizen from the seven countries included in Trump’s ban has participated in a recent terror attack against the U.S. Most of the 19 terrorists who carried out the Sept. 11, 2001, attacks were from Saudi Arabia; the brothers who carried out the Boston Marathon bombings were from Chechnya; and the husband and wife behind the shooting deaths of 14 people in San Bernardino, California, were from the U.S. and Pakistan.

I came to the U.S. in 1983. If Reagan had crafted an arbitrary ban similar to Trump’s and included Mexico, I wouldn’t be here, all on account of an unjust decision. People from those seven countries are being arbitrarily punished, along with refugees from the rest of the world. They are being discriminated against merely because they were born in the wrong country.

As the old saying goes, powerful nations are judged not by how they treat the rich and influential, but by their solidarity with the weak and vulnerable. The U.S. had a rich and storied history of accepting and supporting immigrants with open arms—until Trump arrived.
