Presidents Kennedy, Reagan, and now, Obama all envisioned a world free of nuclear weapons. The US-Russian START accord, announced Friday, is a next step in that direction, experts say.
A phone call today between Barack Obama and Dmitri Medvedev sealed the deal for the US and Russia to reduce strategic nuclear weapons by almost one-third and to halve the number of delivery vehicles, such as missiles and bombers.
A US Russia nuclear deal on reducing their arsenals has received global praise. But some in Russia worry that President Medvedev may have allowed too much leeway for the US to develop missile defense systems.
The nuclear weapons deal would replace the START accord of 1991. The apparent agreement comes just ahead of a White House summit on nuclear security in April.
