I honestly doubt the menality of some Chinese member here.
If a country did something to you 70 years ago, does that mean they will do the same thing to you today??
Then they come doubt other country and their foreign relation. Where they have no idea how those country work. Say Philippine for an example. Yes, we do kill hack a lot of them when we had American- Philippine war. But what they fail to see is we also sacrafice our own boys to save the Philippine bacon, and Filipino appreciated that for that. Not because we rape their women and kill their boys.
People need to let by gone be by gone, time is never ending, if you hold grudge forever, you soon turn the whole world against you or you against the whole world. Because as time pass by, different country may piss you off or you may piss off other country
