It was Vajpayee and Jaswant Singh who wanted to sign the NPT and CTBT. This is on record - their speeches at the UN and reference in Talbot (former US Ambassdor)'s book.
The deal does not curb our militrary program. It is a civil deal. It means if we chose to nuclear trade with US, we need to confine it within a civilian framework. To ensure we do cheat by diverting these assistance for nuclear weaponization, the IAEA safeguards come into effect.
We have 22 reactors and building another 6 reactors. Half will fall under the safeguards. We chose which reactors will be under safeguards.
The military reactors are kept out of the safeguard. Here we use our technology and fuel or those provided by friendly countries like France, Russia etc for this purpose. Our uranium reserves are limited. So the deal entails us to source imported supply from global markets. This frees up our own internal uranium supply which will be used entirely for weaponization.
The deal does not mean that we have to trade only with the US. It is an enabling agreement that gives the NSG waiver so that we can trade with whoever we want, including the US.
India has thorium and cutting edge (fast breeder) technology - which we can sell, the revenue of which we can invest in expanding our reactor capacity using also imports
