Talking up their Su-30s and Kilos have deluded many gullible nationalists into thinking they stand half a chance. This unsubstantiated sense of ability have convinced many that Vietnam can actually fight and hold off China. Just like many think India can do the same and Australia too. Fantasy self-reassuring is what it truly is because so far we've been hearing this sort of stuff for many years now but strangely enough, they all just keep talking about how they are able to do this and that and the only reason they don't follow through is not because of their real incapability but rather because they are just too civil and nice Crafty buggers the lot of them. Can't win the real fight, must win the trashtalking so they lick their self-inflicted wounds through words of mutual encouragement and self-assurance and try to convince themselves and each other that they can continue to mistreat and bully China. Humans are truly pathetic worms. An honest and decent man among that group is hard to find. Even the US knows all bets are off in a war so trade war is their most daring effort to date. It's worked against Russia in the past so they are trying to replicate it with China.US was too afraid of China sending another "volunteer" force into Vietnam to invade the North, and China provided huge amount of material and technical support to the North Vietnamese. If another shooting war happens, who can provide the logistical support to the Vietnamese now?
