Russia objectively has the largest nuclear program.

'which car collection is larger, the one with less more expensive cars, or the one with more cars'.

See how that works. The one with more of the 'thing' is the larger. The fact one nation gets more bang for their dollar doesn't change how numbers work.

Again, the US has the largest nuclear program by a long shot. Russia isn't even in the top 5. Please go back and reread the source I posted.
