Yes USSR helped China with their program. As far as India is concerned the Atoms for Peace program was abused by India to help build the bomb, this is true. This program was designed to harness nuclear energy for peaceful purposes and after the test of '74 the U.S. placed trade sanctions lasting 25 years. Poor example, but good try.
You are blabbering just for the heck of it... The bottom line, it was USSR/RUssia Canada/USA that proliferated to China and India and they went nuclear. From the past experience, given Indian track record to abuse & Cheat US has again put the last nail in NPT coffin and providing same nuclear technology to India. Then there is a little terrorist state in the ME that got its lil nukes from santa.... LOL.... You cannot have your cake and eat it too... Better luck next time.
