It's more or less a currency game.

Majority of the countries that US destabilised, invaded or supported rebel attacks were trying to stop dealing in the dollar currency. Gaddafi wanted to switch to payments in gold and he got killed in the streets. China and Russia also wants to stop dealing in dollars, as dollars gives US the power to control the world in their fingers and do as they pleased.

Imagine the whole world being dependant on a whole currency, the implications of that would be catastrophic if the currency were to evener have been destroyed.
