What Trump did was the way. If you keep them in another country like Mexico unltil their trial which most won't actually win then they know they can't get into the USA and they don't even try. However since Biden won't do that because the jews who run him want to destroy white America and you cant legally use lethal force maybe you could cover the whole border with stink bombs that were so repulsive people would throw up and be sick and not be able to walk.
