Left has no other option but agrees to the N- deal as they cannot face election which is sucidal to left parties as they cannot get numbers as they having today to dictate any ruling colition after electuon.Having the privilage of teaching politics to UPA parteners who are all mostly headless chickens,and also looked after well and treated as first rank VIPs by UPA,the left does not want to sacrifice these luxuraries which they cannot get again after election. Sitting between the devil and deep sea these left parties prefer to sacrifice their policies than facing election.Hence there is no surprise to left parties who have no other option but surrender to N-deal which is dictated by USA through IAEA.
