Obama is set to maintain the U.S. arsenal of 1,528 deployed warheads — almost half of which are on 30-minute alert

"Obama’s Hiroshima speech was reminiscent of the one he gave in Prague, only three months into his presidency, when he announced that he would “seek the peace and security of a world without nuclear weapons.” "But that was as far as he would go. Obama is set to maintain the U.S. arsenal of 1,528 deployed warheads — almost half of which are on 30-minute alert — despite a 2013 White House assessment that he could safely reduce the U.S. arsenal by a third. Obama is also pushing for a $1 trillion effort to replace the U.S.’s entire stock of long-range strike bombers, cruise missiles, nuclear submarines, and land-based missiles – which experts have said is sure to cause an arms race."
