Negotiations have started between the govt and the opposition. The Tata threat is a pressure tactics -- though understandable. The following will happen in short order.
1. A deal would be reached about farmer rehabilitation, after Mamata Banerjee effectively gives up on the demand of returning 400 acres.
2. Despite this Mamata Banerjee will declare this as victory, and organize a "Singur-victory day" rally in Kolkata. Might even become a yearly event like her "martyr's day".
3. People will derive the right conclusions, and Mamata's dream of entering the Writers will be further away than when she started her agitation.
4. Nano will roll out on time.
On the whole given the fact that democratic opposition is a good thing, in hindsight it would not look as depressing as it does now (notwithstanding Mamata's brinksmanship). This is how one has to function in a democratic set-up -- hopefully Buddhadev has learnt his lesson and would be better prepared next time.
