And how many American owned assets are there in Mexico? Expect them to get taken away.

Mexico will bow down to the will of Trump.

This response shows that you have no answer. You haven't even considered whether it is actually morally right that one country can take by force assets from another. That makes America an aggressor and is a good enough reason to declare war on any country doing this. There would likely be sanctions against America. Anti-American sentiment around the world would increase dramatically (the bit outside of America that supplies you with lots of oil and money and keeps you lot in a lifestyle to which you have become accustomed). Expect massive economic consequences of such an action, even from your ordinary member of the public.

And all to build a practically useless wall?

And who's going to pay to maintain this wall? How is America going to stop multiple parts of it getting blown up by drug and people smugglers? Are you going to have surveillance over every metre of its 1933 mile length? The ongoing costs far outweigh the initial costs.

Do you expect there not to be consequences against America from the rest of the world?

Yeah, our supply of crack will be cut off.

So the wall will extend across the Atlantic and across the Pacific and into space will it? Have you heard of these new fangled objects called boats and aeroplanes?

Also, you do realise that an alternative home-produced drug would be fill the market instead?

I think you'll find that it was America that paid, one way or another.

We are already paying the price for not having it.

All that cheap labour flooding the country, if only companies had a choice in not hiring Mexicans ...

For a fraction of the cost America could enforce stricter controls on hiring legal workers and harsher penalties on companies that don't.
