Russia had and still has the most nuclear weapons in the world, totalling about 13,000. The U.S.A. has a lot less, however, they may be slightly more developed.

The US also has a more robust nuclear deterrent system, mostly in the form of SSBNs, nuclear submarines carrying ballistic missile's and the B2 stealth bombers, which can fly intercontinental missions while carrying a nuclear payload. And as far as I know, the Minuteman III ICBM systems are the most advanced nuclear delivery vehicle in use today.
