US and Russian nuclear arsenals

US President Barack Obama and his Russian counterpart, Dmitry Medvedev, signed a landmark nuclear arms treaty in the Czech capital, Prague on Thursday.

The treaty commits the former Cold War enemies to each reduce the number of deployed strategic warheads to 1,550 - 30% lower than the previous ceiling. Here is a breakdown of their respective arsenals.
