Yes, Russia is far less rich. But the superior might and reach of the US (or EU or NATO) tends to be to leveraged to overthrow countries that are much weaker, such as Libya. Meanwhile Russia's expansion into Crimea has only been met with sanctions, and they have carved out a growing sphere of influence in Syria by helping Assad turn the tide in the civil war.

That's why I called it semantics. With nuclear weapons and the logistical capability to deploy them, asymmetric economic power doesn't matter as much.
