Geopolitical relationships and people to people sentiments between countries are artificially constructed over time. Tying back to the original comment, Japan, Germany, South Korea didn't "naturally" become friendly over time, it was a carefully cultivated process. The process doesn't work on speed of infomration transmission, but speed of demographic transition. Anti-American forces in those countries didn't get "converted" they were sidelined and repressed so their influence does not transmit to next generation. I'm saying friends western system/hegemony has build are one good fight from flipping.
