This is the problem with any coalition govt with heterogeneous composition.Idealogies are different.Aspirations are different.Wave lenghts are different. They have no common mandate nor a common bondage.The only bondage they had while forming the govt was to keep BJP away from power and they could succeed in that.All of a sudden have left parties forgotten this?If so,for what valid reason?In what way does it(N.Deal)conflict with their ideology ,if any?Are not the national interests to rank over all other things?Is it not silly to threaten the Govt for every silly & sundry reason?Since their support is from outside & they donot form part of the Govt,every credit or discredit accrues to the govt signing the deal.Then what is their problem?They should note that in the ensuing elections,if their attitude & approach continues like this,their strength gets reduced from the present double didgit to single digit.Are they not aware of what their own veteran Jtothi Basu said just a few months back about working out of socialism in India?He categorically told that socialism will not work in India.When will they learn lessons?Strictly speaking,like any other politicians of any other party,communists too are only property makers these days in stark contrast to their being sacrifiers of all their personal properties too for the sake of party & its ideology during its initial days in the country.Their game of shooting from the shoulders of the party's name will not work for all times.
