What are the advantages of stopping all immigration and international travel to the USA?

The rest of the world would be free from your godless philosophies, false religions, bloodshed caused by you drug addiction and so many other evills you have infected the whole world with.

Immigration isnt stopped, the problem is illegal immigration and proper checking from terrorist countries.

Its not the 1980s anymore. Today people want to blow themselves up in public places, you have to up security for the country. Plus people are trying to smuggle bomb making equipment in, thats gotten smaller and more advanced and can be moved around easier now, the 1980s are long gone as far as that goes.

Just look at sweden and europe and how many terrorist attacks and rapes now occur there, they now realize the mistake but are screwed now that people are embedded everywere. Thats not going away and is not easy to clean up.

No tourist dollars.
