Russia has pretty nearly decapitated itself, all on its own. Their culture of mass corruption consumed its armed forces from the inside out long before the ill-fated attempt at conquering Ukraine, and all that's left is a sickly shell that even NATO's 2nd and 3rd generation old weapons are decimating on a daily basis. Aside from the nukes, they're a toothless bear.
Will they use the nukes? Who knows. But being China's little bitch won't change that one way or the other.
This is a demonstration from China showing that they own Russia, completely. But dickface putin is too arrogant to understand that he's being led around by the leash. Truly pathetic but from a threat standpoint, there's nothing to it. Hollow, and empty.
