Iran was secular, Afghan was secular & FYI Pakistan was secular.
Yeah thats true.
Lets examine in more structured way.
-> two possibility for Indonesia
A) remain secular
B) become islamist
-> For option A, we have two option:
A) sell weapon: will make Indonesia dependent on us, hence can not go against us
B) dependent on china/pak: may go against india
-> option B:
They will disgust us and hate us , so anti india in both case, if we already have sold weapon, then our secrets and tech will go to china/pak.
Islamism is growing in Indonesia, but possibility that it will take over Indonesia is not very high
So it means we need to sell them weapon, but not the top of the class, but atleast what chinease will sell them.
As Indonesia too can not become pro china directly (they can become pro pakistan definitely ) as they hate ethnic chinease and on top of that, ethnic chinease are Christians.
And in past, there was a massive anti-chinease genocide by Indonesians, and islamist hate ethnic Christian chinease alot(it their local ethno-religious issue).
