Political consideration is always determining Indonesian Defense co-op agreement. This's already being done from Soekarno's and Soeharto's regime time. Both dictactorship like it or not mold Indonesian Political practices, and Defense in the end will be determined by that rather than users choices.
Thus no matter how far TNI as users doing more professional studies, in the end Political choices will be taking precedent. Base on my observation as Financial Industry practicioner (and this's not just in defense), Indonesian priority on any government projects take this kind of priority order:
1. Political Choices,
2. Budget (money trails) availability,
3. Users recommendation.
It doesn't means the lower priority can't influence the higher priority. However the influence of lower priority order has to be considered on how getting the higher order execute.
The problem is always (and this's not just for Indonesia, however more matter in Indonesia), the second and third order more or less in clearer cut position. Either you have it or not. While the first order is more 'Grey' area (for Indonesia case can be 'murkier'). Political consideration always having more influence not only with Political reality but also Political circles interest.
Take example on High Speed rails project. The users (Indonesian rail road company) was known by us in Financial Industry already shown preference using Japanese vendors and tech rather than Chinese ones. The financial calculation shown Japanese offering actually more clear cut on potential problem in project execution. However the Chinese offer end up being taken,on consideration it's cheaper and only base on B to B arrangements (between Chinese vendors and Indonesian SOE), thus in paper they (present administration) tell the public it will not going to use State Budget. While Japanese offer asside more expensive (in paper) also demand backing from State Budget.
Turn out this project need additional USD 2 bio (so far) that in the end has to come/guarantee by state budget. Moreover the cost overrun is part on what Japanese already calculate. So even with the second and third order already shown preference, it's the first order that in the end will win.

I'm not going to discuss the Political choices behind this, however just put is as example how Indonesian Strategic projects (yes High Speed rails project is considered as Strategic one), in the end will be determined by the first priority order. Political choices in the end will determine the courses taken.
On defense Geopolitical situation seems already shown where Indonesia going to. Indonesia so far decide not to challenge CAATSA, Indonesia defense circles decided to build closer relationship within ASEAN five, Australia, NZ, Japan, ROK, and Western alliance. However at same time still maintain relationship with China and Russia eventough on relative lower degrees then before. This is shown on recent defense co-op and procurement picks.
This doesn't means on practice Internal ruling parties circles of interest will not determine which Western sources going to be taken. However for Air Defense Assets, I do see Political and Geopolitical reality means some US procurement has to be taken.
Thus despite current administration closer relationship with Frenchie, doesn't mean French position already safe. After all if changes in defense co-op can happen in Australia, imagine in Indonesia. I do see in the end some US assets will need to be procure. Not only due to users preference (TNI-AU always shown preference to US assets), but also to Geopolitical reality. How they are going to prioritize based on budget consideration (the second order/money trails), that's will be interesting (at least for me as Financial people) to see.
