True, one party communist state(and other one man rule dictators) has it's benefits, but also disadvantages, since it's good when things are going well, However when things go wrong it is a disaster for the whole country. Just look at former one party communist states/one man rule countries who collapsed in the past from Soviet Union to Romania to Libya etc, it had devastating impact on the country, since communist one party state regard themselves as the country itself. There is no distinction between political party and state/country. Since the communist party regards itself as the country itself and sometimes even puts itself above the country, so when that party collapses its creates a huge vacuum and leads to even more instability as different actors jostle for power amid their own greed. Same almost happened with China in the 1990 Tiananmen uprisings, the country could have gone in a totally different direction had the uprisings succeeded. So yes authoritarian dictatorial one party states have their benefits but also their flaws, and when their fall comes NOBODY USUALLY EXPECTS IT, since it's happens spontaneously and fast.
France will harshly dispute that assertion.
Indonesia has been quite passive a leader in ASEAN to be honest. Indonesia needs to be much more assertive and needs to show its leadership in a more open role than taking passive stances in most crucial issues. That's how a leader should behave, just being the biggest doesn't means you are automatically the leader, you have to earn and show it.
However, i don't think Australia will allow Indonesia to be more assertive in this role, since it wont be to Australia's interests either. So therein comes the dilemma as well.
