Maybe the reason you don't hear anything "else" on the subject is because you didn't hear such a thing in the first place before. What is the T-90 scam? Does any allegations of a scam exist even in the media? Many people have criticized the purchase, but there is enough justifications for it too. However the point is that no scam or corruption charges have been leveled on that issue. Except in the minds of PDF members.
Going on ranting directionlessly about everything in India being corrupt beyond redemption is a pointless exercise - but then, to invent scams that don't exist is taking the disservice to another level.
Of the real problems that do exist in our defence procurement policy, a lot needs to be done. But that is not upto any one individual, whether anna hazare or any other prophet who can magically solve all ills. You are right it is not a political issue - so how is anna hazare going to help, since it is not a political issue, and at present anna is not in the military or ministry of defence, and won't be in future? If it is not upto elected representatives (and I agree it isn't), in what capacity can anna hazare help to change the defence procurement policy? Why is he being mentioned in this thread at all, and why all this semi ficitious and gloomy rants?
