Sadly, I think you've as much hope of convincing them as you have of convincing Brexiters that they miscast their votes.

The US won’t understand that it isn’t God’s own country, leader of the Free World, etc. until it has gone the way of all other empires and had its arse handed to it financially by the next power to rise — when they find that they can’t get the better paying jobs overseas because they can’t make the points required to get a visa … when US companies are bought and owned wholesale by foreign corporations and they can’t get high-ranking jobs in them.

Nor the UK (or, rather, England) that it isn’t even regionally significant, let alone a global power, until it has once more found itself the sick man of Europe had to go, cap in hand, to the IMF for a loan.

Short of some major disaster with the Euro, the latter shouldn’t take too long to come to pass, but even then the chances are that any ‘stimulus’ investment by other nations (China?, India?) would bypass the UK except insofar as the few Brexiters with spare cash were in a position to repeat in the West the ‘landgrab’ that took place in the East after the fall of the USSR and satellites and thus benefit from it by proxy.

The former will probably take a while yet: I don’t see Apple needing to sell itself to the highest bidder any time soon and, unless governmental collapse and social unrest in the US were to see a corporate flight to greener fields, I can’t really see any other of the big corps doing so either (for profit sure, but not out of necessity).
