Indonesian diplomat actually is quite good, and has proven track record. Our specialty is backdoor silent diplomacy. But it is not without flaw as we are sometimes met with some hard stubble. The flaw of their mission profile lately is
1. Indonesian foreign policy has been kidnapped by moral issue in which had little benefit for Indonesian society as a whole (the most notorious is Palestine issue) and given less room for more strategic and tactical maneuver on the table
2. Indonesian diplomacy doesn't have sound backing at home, well i mean real hard power backing policy, Indonesia actually has economy weight in which can be translated into real hard power for negotiation like JICA and Japanese economy Investment, also real military power in which can be used to protect Indonesian interest aboard (like how Turkey using their newfound military prowess to be involved in Libya, Syria and Somalia). More card on the table to be used for negotiation is much more better, case is , i think we would not lose Sipadan and Legitan if only at the time we push for forced military occupation just like how Russian Occupy Crimea or Chinese build outpost base around South China Sea and not trying to resolved them by Internasional court arrangement as long as Indonesia has considerable military might and economy power.
3. Indonesian diplomacy corps has acute lack of intelligent based information resources, in which most of the cases they are involved is based on fire fighting method not in the prevention method. Current OSINT community should be the places our diplomat should dwell and trying to learn as much as possible, but sometimes people can be pedantic and feeling much superior
