I must say I don't share at all the wonderful Trump welcoming atmosphere in these parts!
I think he already signaled with regard to the Indian visas, that he has no objection to mass immigration, only illegal immigration which is only a small proportion of the whole. But yes he will make quite a fuss on that now which disguises his real wishes and also will help develop further the surveillance state, since they can now introduce all kinds of such measures claiming it is only to track down illegal immigrants.
Personally my guess is that he might be the 'first contact' President, meaning the Occult inspired alien hoax, maybe in the summer, and maybe WWIII might kick off about December or thereabouts, although I admit I am only guessing.
The only thing they are sincere about is a little rolling back of the 'woke' agenda, like with respect to transgenderism and some parts of extreme feminism. This is needed to inject a bit of credibility into the Presidency, and armed forces, before said war starts.
