But Biden does just the opposite. The president is not trying to stop the flow of illegal crossers. Instead, he is trying to accommodate the flow, scrambling to find housing and living arrangements for those coming in. The message has gotten out to the world, and the world is coming. The president, and members of Congress, and most Americans would never tolerate such a situation at the nation's airports or seaports. When anyone flies into the United States from abroad, landing at, say, Atlanta Hartsfield or Chicago O'Hare or LAX airports, the United States government demands that every single person present documents showing that they have a legal right to enter the country. Would anyone advocate scrapping that system and letting anyone and everyone enter, with or without documents? Of course not. Yet that is the situation that Biden is not only tolerating but encouraging at the border. It is, in a word, insane. The United States, which like other countries has developed elaborate procedures to control who is able to enter and leave the country at its airports and other ports, has thrown the whole system away at the border. Starting with the presidential campaign and continuing through his time in the White House, Joe Biden has sent the message that virtually anyone can enter the U.S. and be allowed to stay. The crisis at the border is the result.
