It is not Russia's business. Ukraine is a sovereign country and what alliances it has is its business and not Russia's. That is the definition of sovereignty.Russia would never have allowed NATO’s presence in Ukraine
US would make it (and does make it) worth Mexico's while not to do that. It would definitely not invade Mexico and murder thousands of its citizens. You are full of crap.Roll on expansion of a hypothetical Chinese and Russian military alliance in Mexico to help Mexicans defend themselves from any possible aggression from the US. Just imagine what the US would do.
