Bush is pushing for the treaty, so that he can show to his country that he has done something good for his country. This treaty is very good for the nuclear power businessmen of USA. That is the reason it is exerting continuous pressure on the govt to sign it in its present form.
However we should not sign the deal till it is categorically declared that Hyde act will not b applicable.
UPA is now pushing for it to divert the attention of people from rising inflation, farmers suicide etc.
Why does it not propagate family planning making one child as norm on the lines of China, as population explosion is a big problem of the country.
