I think, the Prime Minister should discuss in detail the nitty- gritties of the Agreement rather than being adament.Why he needs to rush it through like this and why he cannot take the suggestions of all party representatives and think for the interests of the country.I dont think, US congress would allow such a pressure from any one else like We allow them to do.There is no urgent need of signing it even if we need to take some more time by doing more deliberations, analysis of plus and minus of the deal particularly with our Scientists community who know better than the Politicians
