Send Karat's and all Communist comrades' sons and grandsons to the war front. Put these guys on the Arunachal Pradesh border to see what chinese are doing, how their new Qinghai rail line into Tibet is being extended closely to almost touch indian borders.

Atleast Chinese communists know what they are doing and why, most (I respect a few commies in India too, who act as reins for otherwise capitalist and vily politicians) Indian commies are leftovers with borrowed idealogies and zero brains...
