Basu has seen the shifting of the wind - the vast majority of the masses being for the Indo-US N-deal and against the Commies, especially their threat of bringing down the govt and forcing early elections. So to forestall any mass defection of it's cadres and middle-class sympathisers, he's rushed in to change course away from the gathering storm and save the day for the Commies, by proclaiming he too is for the N-deal. Wow, what a hero! He might just leave Yechury, Bardhan, Karat et al 'red-faced'.
