All I am saying sir, is that given the situation the MoD/IAF now face- a single vendor situation, would you consider it s success or failure if the new DM cleared the deal.
A failure of course, because the aim was not to select a replacement as soon as possible, if so Arun Jaitley could had done it already, but it was to get as many privat industry players to participate and create competition in the defence field, in this case the licence production of a foreign aircraft. That's why Jaitley extended the timelines for the bids and why Parrikar is having issues to take a decision. So if that aim is missed, it's a bad situation that leaves us only with 2 possibilities, either to face the problem and say it didn't worked out as we wanted but the forces needs the aircrafts, so lets move on. Or try to change requirements of the competition to get more alternatives.
For example, as you pointed out (and as I am saying since years) one can increase the potential order by combining similar requirements of other forces (which however the forces must agree too and IN might be a problem here), becaused increase production => increased profit. Another possibility is to let HAL try to team up with a foreign partner, for example Saab which would be a logical choice. Saab offers 2nd hand aircrafts from the Swedish forces for the initial delivery, but since they don't produce the Saab 2000 anymore, they are looking to divert the complete production line to India. HAL already has production capabilities, so could easily build the aircraft, while many other privat partners has to start from scratch. That would at least give one competitor to the Airbus/TATA team up and we can select the best offer at the end.
My only point about the past GoI/DM is that we know for sure they would have let this deal remain in stasis indefinitely as a single vendor situation would have induced an immediate "no" from them.
That's your negative point of view of the former government speaking, ignoring that the current government shows the same aim on avoiding single vendor situations and reportedly even wants to make exceptions in banning procedure if there are no alternatives (not officially confirmed though). You can't do as if that's a new policy only to make them look good. If they take the option to move on, it's a forced solution contrary to what they wanted.
Wrt the MoD remained in stasis claim, take the VIP helicopter competition as an example, which in the first evaluation nearly ended in a single vendor situation (leaving only Eurocopter complying to the requirements), which lead to the requirement changes and a 2nd evalution. We have seen the same in howitzer tenders too, which at the end however mainly were scrapped because of corruption issues within the army.
