The strength of America post WW2 comes from its network of allies. Through that network, the US enjoys the benefits of a global empire while minimizing the cons of actually running one.
Trumps obsession with tariffs and trade wars attacks the core of what the American post-WW2 order which is easy access to trade.
I’ve often called BRICS a failed project, but the Trump presidency offers a unique opportunity to start the foundations of a new global trade network that isn’t dependent on the United States.
Will that be through BRICS though? Probably not. But time will tell.
