50% back is huge exaggeration bhai. HuuuuuuugeA!.
50% is the offset announced by our defense ministry.Now I dont think they can lie about something like that.
If we rejected this deal Rafale will shutdown once and for all with huge loss.We know they cant give use some rare sensitive tech .But these 50% will spike up our industrial capability .If you want to develop your own next gen indigenous jet you should need your own capable private defense industry .That would be the another major contribution of this deal.
