Long story short russia has many advantages over the USA, EU and china if an economic crisis hits.
First, the west says they will cripple Russia with their sanction power. If the world cut off its business with Russia they will not survive. But it seems the world will not survive if Russia cuts off its business. Right now factories are shutting down and transport cost is spiking but if Russia doesn't export wheat then people will die of hunger. Canada and USA are also wheat suppliers, but the amount is not enough to fulfill world demands.
Does the world have 10 weeks of wheat supply left after that what will the west do? They will let African country to wipe out their population because of food shortages? Maybe this time the war will be for wheat, not oil and gas.
