Under President Donald Trump, the United States is seeking to put an end to mass immigration worldwide and make border control «the cornerstone of American national security,» according to a White House document published on Friday. The document states: «The era of mass migration must come to an end.» It also adds: «We must protect our nation from invasion—not just from unregulated migration, but also from cross-border threats such as terrorism, drugs, espionage, and human trafficking.» Border security is the most critical element of national security.»
