I don't have a good feeling about this. If we're really going to take care of business, it's going to take some radical changes. . with a lot of resistance and it may get hot. If we don't we gradually die. Man o' man.
The more I think about it, let's take care of business and get it over with. . Not CWII but new radical laws, restrictions, shut down the mosques, no muslim immigration, really crack down on the communists and other domestic enemies, you name it. . . a slippery slope for Trump. . you think the left and muzzies are agitated now. . . do it all through EOs and laws passed by Congress, National Security, domestic enemies, etc.
Some pretty radical stuff to be sure but as you look out 200 years, as our Founders did, what do you see if we do nothing?
Not even a hundredth of what you propose would survive court challenges unless you plan to ignore the Judicial Branch and only use the Executive and Legislative ones.
If President Trump stopped all immigration for an indefinite length of time, he could avoid all challenges - no discrimination based on gender, race, religion or nationalities.
