ha ha ha ... you are creating these "facts" as you write. BJP was never tough with the Bangla deshi govt. they were always trying to improve their image with neighboring countries .... never tough, always mild.
It was Manmohan Singh in Narsimha rao's cabinet that jump started India's economy. NDA just carried on those plans ... they did nothing new ... OK they did let Modi watch riots and themselves stayed in inaction over disciplining Modi. well it got them votes though .. LOL
