Pakistan Expanding Nuclear Program
India currently has an estimated 30 to 35 nuclear warheads based on a sophisticated plutonium design. Pakistan, which uses a simpler, uranium-based warhead design, has sought for years to modernize its arsenal, and a new heavy-water reactor could allow it to do so, weapons experts say.
“With plutonium bombs, Pakistan can fully join the nuclear club,” said a Europe-based diplomat and nuclear expert.
