I think, it will have lot of repercussions if both the countries sign the agreement now and at a later date India decides to conduct the tests.. 1) it is a commitment of huge sums of money. 2) With this commitment, we will be married to this technology which will be very costly in case we have to come out of this. Costly in terms of both committed amounts and also lost opportunities otherwise. 3) It might also attract imposition of regulations by other nations in that event, which will again retard our progress.
I think it is better to take more time now to have a clear understanding of the deal if it suits all our requirements now, rather than repenting later. It's after all public money and public interest that political parties are putting at stake. So, the long term perspective is better than shortsighted hastiness.
