Make no mistake the world is currently engaged in a financial war and the ruble collapse is just one battle. The 2008 Great Financial Crisis ushered in a new currency war that has morphed into a financial market war, with oil as the weapon of choice.

I am not trying to be a fear monger, I am simply pointing out what is occurring in the financial markets. In the beginning, a financial war seems like a no-brainer, i.e., use financial might to damage your enemy's economy. The flaw in this logic is it assumes no impact on the economy of the attacker. In the age of open economies investors are correct to be concerned about the collateral damage.
