For some reason, hundreds of people, mainly residents of Honduras and other nations in the Central American isthmus, believe that they have the unchallengeable right to enter the United States on demand and have banded together in a caravan and are walking across Mexico toward the US border with the hopes of gaining entrance, and eventually permanent residency, legal or otherwise. None of us will disagree that the US is a desirable place to live, and at the risk of being termed a "nationality bigot" we will make the observation that it must be a far more attractive place than the nations the caravaners originated from (or else why would they be abandoning it to come here?), but there are rules that should be followed and the caravaners and the thousands like them who cross the border on a weekly basis do not follow the rules that the US historically expected immigrants to follow and which every other nation in the world requires be followed. Let's face it: being in Fenway Park or Dodger Stadium for the World Series is desirable for many of us, but see what happens if one were to collect a couple hundred of his best friends and storm the gates at one of those ballparks. We doubt if management would open the turnstiles and grant admission; and if they did, the folks who had paid for the tickets to that game and to those seats would not take kindly to their displacement by folks who had no tickets.
The identical principle applies to entry into the US by those who have not followed the rules, and if a couple thousand of people without tickets are admitted to a baseball game, that ends right there; but granting free and unrestricted entrance into the USA grants many other privileges, rights, and opportunities far more permanent than one ball game.
The Trump administration does not accept these caravans with anything like the resigned tolerance or compassionate passivity of previous administrations, and the President's displeasure apparently has gotten the attention of the Mexican authorities, who by the way under international law should be the country accepting the caravaners as refugees, and not allowing them to travel unimpeded to a third country.
We remember fondly the old "Rocky and Bullwinkle" cartoons from the early 1960s, and in one of them the villain, "Fearless Leader," had gained entry to the US. Another character made a comment about how he could get in under the immigration laws, and he replied, "immigration laws are to keep the honest people out." It was a funny line in 1962, but today it is far more appropriate and not nearly as humorous. How could the writers of a cartoon over fifty years ago be so perceptive and our politicians today be so dense?
