And in 3 months Russians will starve to death as oil and gas make 60% of their economy.
Russia is one of the world's biggest exporters of cereal (esp. wheat).

If anyone is going to starve, it is going to be the Egyptians who depend a lot on the Russian wheat. It is true that Russia imports a lot of fruits, vegetables, dairy.etc. But these products are produced not just in the US / EU. They are also produced in countries such as Brazil and Argentina as well.
