They don't need to.Indonesia is the world's largest Muslim nation-they will have plenty to give in Aceh,which is part of their territory.
I LIVED in Aceh for four years. I have also lived in Saudi Arabia. I know both places probably better than you do.
I own a home in Indonesia and just returned from there today.
The fact is that Saudi Arabia has funded their filthy hate-spewing madrassas to the tune of billions of dollars. For their co-religionists in Aceh, they are now making avialiable $10 million, 1/35 of the amount pledged by the United States.
That's why I made the sarcastic remark that Saudi Arabia was sending 50 Korans. It was a JOKE, man!
