Forget 2 years the indian economy would be crippled in a matter of weeks if all muslim countries embargoed it.
Indonesia is a sleeping giant, but the people need to wake up. Indonesia should be far stronger militarily than it currently is. Pakistan has a lot of weapons it can offer. I know indonesia has many ventures with South Korea which pakistan can join as well.
Let alone our trade potential which is huge. Pakistan can export far more to Indonesia than it can to GCC, Iran, or turkey combined due to Indonesias immense population and cultural similarities.
Indonesia is pretty much a muslim majority India that Pakistan has friendly but dormant relations
I believe spending 9 billion USD for our armed force which is around 0.8 percent of our GDP is already quite high for Indonesia case. As you know Indonesia doesnt have big threat in her region since our country is considered as the big guy that has more possibility to bully than being bullied. This is one of the reason Singapore and Australia spend quite big for their defense budget. Next year we are going to spend 10 billion USD for defense if the budget plan can pass the parliament.
The only country that we could worry is China, but considering our dispute with China in SCS doesnt cover large areas and so far there is no oil and gas ever been found there, so Indonesian strategic planner see Indonesia is still relatively safe for the next 15 years, the analysis that I also agree.
The main target of Indonesia, currently, is more on economic development. Even previous and current government spend so little on R&D due to the focus on infrastructure and other post. Personally I would prefer Indonesian next leadership to pay more attention on R&D and keep defense spending at 10-12 billion dollar until 2030.
Indonesia actually is quite active in ASEAN region and also has foreign policy that has Islamic tendency like its work and advocacy toward Palestinian, Myanmar, and Afghan issues. Indonesia also doesnt have any afraid to call Chinese and Indian ambassadors for cases related to how they treat their Muslim. Latest action is to question China foreign minister about Uigyur issue in December last year. This action IMO makes China a bit angry which then resulted in China Coast Guard encroaching our EEZ in January, although Indonesia doesnt back down and respond back by saying its publicly support UN tribunal ruling that back Philippine claim over China nine dash line.
Indonesia also pressured Australia when Australia decided to put their embassy in Jerusalem. Pretty much other nation within ASEAN will be hesitant to do the same thing like Australia does because IMO of Indonesia influence on the region. This is why Singapore doesnt do that despite that nation has close relation with both USA and Israel.
Regarding Kashmir issue, I believe Indonesia will support Pakistan idea to have foreign ministers level meeting in OIC. Current situation in Kashmir IMO will give more reason for many Muslim leaders to act harder on India.
People can say us as sleeping giant, prominent Muslim country, it may be true, but I would say that since Indonesia geographically is located far away from Middle East, where most Muslim problems happen, it will have less leverage to do something substantial in that region, let say to mediate factions in Yemen or Libya, although for Afganistan case, Indonesia involvement on peace process is appreciated by both Afghan government and Taliban leadership. Taliban leader for instant has come to Indonesia from Qatar to work on Indonesian peace deal initiative. Previously, under Soeharto, Indonesia play major role for peace process between Muslim Moro and Philippine government.
Talking about Indonesia policy on Muslim world in the next 10 years, I can say Indonesia will keep playing low profile foreign policy and dont have any ambition to challenge current political infrastructure in the Muslim world which is OIC. So far Indonesia doesnt have any resentment toward OIC like Pakistan does and my country seems to be quite satisfied with that organization.
We could some how have leader that has ambitious agenda on international politics like Soekarno, but from what I see on current potential leaders that could win 2024 Presidential election, there is no one that has the same caliber like Soekarno.
