Correct, just like 111 years of nuclear research haven't gotten us a useful fusion reactor. Keep in mind that while the world of 46 years ago wasn't as advanced as today, it wasn't exactly backwards either. Even factoring in the accelerating nature of technological progress, some things simply cannot be expected to happen by the year 2053. Sci-Fi has a bad habit of overestimating technological progress, but I'd like to avoid that pitfall as much as I can. I'll educate myself on the subject of Indonesia some more, but the simple fact is that gains made by conquest tend to not be as useful as gains made by diplomacy. I'm not so much saying that you "can't" take Indonesia by force, but rather that such a conquest wouldn't make your nation that much more powerful on the international stage.
