I'm sorry bro, he was touted as some god-send for DM but he is not that guy, he doesn't even seem to be a particularly wise leader. Inept maybe too strong a word but he is definitely not a revolutionary.
Additionally, it isn't the job of the DM to dictate the defence strategy/plans to the military- the military comes up with their wishlist/plans/strategy, the Govt simply tells the military the overall strategic imperatives, not how to get them done.
Nothing the DM is doing is changing the way the IAF plans/thinks, he is simply meant to facilitate that and here he is failing (all three services) miserably.
It was not all Dassualt's making, the Indian side has to take responsibility for quite a few of the issues that cropped up on the way.
Anyway, this new Rafale deal is a govt-govt agreement and thus things are moving far swifter and will see a happy conclusion before long.
