I really hope you are right in your conjecture of MMS somehow overcoming Left "ally" opposition to the deal. I really do.
Call me a pessimist but you know what I get this weired feeling that MMS has morphed into a self-serving Indian pol just like Lallu or Pawar and will use the next few weeks as the occasion to ceremonially bury the deal and continue as the PM for rest of the term (of course Karat and Sonia permitting), national interest be damned.
