It also foolhardy to generalizing geopolitics dynamics in this case. French is better diversification then Russia for us, to think that we would be safe if we go all US made is also debatable if not questionable. For now its our best bet imo.
Money talks, but National interest isnt all about money. Nation/regional security, natural resources, geopolitics, etc, is also count. By having Indonesia as one of their biggest and first user of Rafale in the area giving them 2 things hands down. Direct/indirect Influence over Indonesia and region, also more tight diplomatic and political relation to us, etc. One thing I know that makes a huge different between Taiwan and Indonesia is Taiwan doesnt host Trillion dollars worth of multinational ships cargo venturing over their teritory. That alone giving us leverage way above Taiwan.
