We in the West think of peace as society's default position. War is a temporary state of affairs that happens when peace fails. For us, war is something that has a beginning, a middle, and an end. When it is over, win or lose, the warring factions lay down their arms and resume their normal lives.
Russia does not have a modern economy: it's a petro-power. The only thing it sells that the world wants to buy is oil and natural gas. When was the last time anyone bought a Russian computer? A Russian car? A Russian cell phone? Russia is so dependent on high energy prices that if oil falls below $100 a barrel, the Kremlin can't meet payroll.
