When did we say Pak has no right to develop nuclear weapons. India doesn't have moral right there. North Korea had signed NPT before. So India has every right to oppose its nuclear development.
No, india doesn't have any right to develop nuke.
india is not recognized by the NPT as a nuclear weapons state, india is expected to sign the NPT like all other 180+ non nuclear weapons state.
by having the 1998/1999 tests, it has been widely observed/concluded that india so far doesn't have any proven ability on h-bomb, not to mention the absolote lack of delivery systems. india is not going to be able to afford to have more tests as again it will be strongly condemned by the entire world.
the chance has already gone, india is not going to be able to build and test its nuke.
