The real purpose of the carriers is not to fight a war, but to assert control of sea lanes. In a globalized economy your country needs access to maritime shipping lanes to survive. The carriers basically act as an area denial threat, preserving the ability of the US and its allies to trade and prosper, denying that to anyone who messes with them. If Russia and China decide they're going to get together and be super trade buddies but the US denies them the trade lanes with everyone else, that's fine, they can share food and oil which are certainly important, but they'll still be broke and their economies will still collapse, especially China's which is super export dependent and seemingly approaching collapse right now anyway. China needs huge exports to survive in its current state and Russia doesn't have that much purchasing capacity.
