You participated in 1938 because Japan retreated, so you were allowed in without any quali games. And then you lost the first game (it was a straight KO bracket) 6:0. The team still relied on structures and partially also players from your Dutch colonial masters, who weren't even a football power themselves back then
But with the World Cup expansion, you should be able to compete for spots. Things are already looking promising now, don't they? You "only" have to develop your own talent now instead of relying on hapas. Surely you have some decent talent you can find on Java at least, as well as the money to nurture them. Indonesia seems surprisingly passionate about the sport
Maybe you can play a role in establishing your country as a serious football nation eventually - who says you can't be a manager?
