Russia President Vladimir Putin has openly accused the Saudi government of orchestrating a form of economic terrorism by glutting the oil markets with supply. While most Americans are cheering over the lower gas prices at the pump, a growing number of experts, politicians, and commentators are quietly siding with Putin's opinion that the lower prices aren't necessarily in our best interest.
Russia's economy is directly tied to oil; when oil prices are higher, the economy (as a whole) tends to function better.
