Trump threatens BRICS (9 emerging economies including India, Russia, China but also Iran and Brazil) with 100% Tariffs if they break from the USA dollar. Russia accuses Trump for "weaponizing the $".
My take: I strongly dislike Trump - and I am not a USA citizen.
That said, from an American perspective the threat that he would go for such tariffs to punish those upstart economies will make them think twice. And in my opinion, it will effectively break any budding support for such a move.
Trump, being an unpredictable madman that would not think far ahead to see how destructive such a thing as 100% tariffs on India/China/Russia/Brazil would be for his own people - nor he gives a crap for the hardships of the 'plebeians' - could do it. Or at least, there's a significant chance that he would do it. And that makes this threat work.
Thus, India, China, Brazil, South Africa would not risk it. Russia... perhaps would risk it but it is far less likely and there's always the chance the others would kick out Russia from BRICS just to make sure they don't poke the madman.
And since he may, any notion to move against the $ will be significantly impeded without Trump doing anything. The threat of the Tariffs would probably ensure that the Tariffs would not be needed.
Yes, it is bullying and it is weaponizing the USA dollar as Putin complained.
And that's in the interest of the USA people.
Trump is a bully and a butthole. But a butthole with some good ideas.
It really sucks for those economies to have part of their financial policy dictated by an obnoxious, self-serving bully. But I expect they will play ball and kiss the ring.
They cannot afford not to.
