may be a good point. BUSH may not be risking signing an important deal like at the end of histerm and may leave to new president. Thats the exact reason why even in India, there were apprehensions for the kind of rush and speed this govt is showing to sign this deal.
The main purpose is to divert the people from the increasing price rises, increasing inflation and then trumpet itself that they tried hard to make the deal and time passed away, So give another chance so that we can sign this deal. Typical Congress high drama.
