"Japan was put on trial for waging 'aggressive war' for monopolizing Asia, even while the Dutch, British, etc. had completely destroyed Asian economies only in the past century."

This is ridiculous - there is no comparison between 'The Dutch' and 'The Japanese' incursions into Asia.

The Dutch were traders, with some geopolitical leverage, money and a few ships.

The Japanese literally invaded and marauded most of E. Asia causing millions of casualties, literally destroying cities, taking sex-slaves on mass, i.e. 'Horrors of Mechanized 20th century' - on par with Nazis. Not some localized trade dispute with a pack of merchant marines firing on innocents, 'monopolizing trade of a few sectors'.
