1) Singh forced Sonia Gandhi. It was entirely his decision to go for the nuclear deal at all costs. He forced Sonia Gandhi's hand in this. 2) BJP too does this. In Karnataka BJP has purchased some congress and JD(S) MLAs 3) Neither will the so-called NDA. Many of them will migrate to UNPA 4) Sonia Gandhi is pro-liberal and it is true that socialistic approach has robbed us of many years of reforms.

So it took that long to understand that science and technology and economic reforms were the rise of western dominance and it would be wise for us to emulate.
