It seems to me #Trump is playing a dangerous game with his latest threat against the #bric nations.
He's probably okay for now, with the threat, but if they call his bluff, it'll start a snowball rolling he won't be able to catch, and neither will succeeding #us presidents. The way I see it is this.
The #usa imposes 100% tariffs on imports from #china so china can't pay #opec countries in #dollars so #opec have to start using another #currency and the circle goes on.
But this circle is really a snowball because it will gradually affect more and more countries, until only #europe can still pay in #dollars for #oil.
Then trump is between a rock (his oil company buddies) and a hard place, his tariff war with #china whose currency is now growing in importance.
Substitute the #renminbi for whatever alternative to the dollar takes off and you have the spiral in clear view.
If Trump is really lucky, the #euro will be the coin of choice, because at least that way, he'll be able to use it too.
This policy belongs to one of those special cases, like having kids, where the choice is literally irreversible.
For all people rail about his other policies they#re not in this class. Admittedly with great cost, they can all be undone.
This one can't. It's a one way ticket.
