Damn, I wish I had bought some rubles instead of dollars
One of the reasons the US has engaged Russia is that it has made it a mission to wean itself from the dollar. Putin openly stated that Russia should sell its oil and gas in ruble. This does not sit well with the US for many other nations could follow in Russia’ footsteps as it is a dominant and powerful player in the energy sector.
More importantly, Russia is the only nation capable of taking on the US and not afraid of doing so. Putin has stated many times that he wants to price Russian resources in multiple currencies and avoid the dollar.
