A leaked US Air Force review has found major security flaws at most US bases storing nuclear weapons in Europe. The probe was launched after an incident last August in which a B-52 bomber inadvertently carried nuclear warheads on a cross-country flight. According to the report, security infrastructure is in need of major repair at several sites. At some bases, nuclear weapons were found to be guarded by private security guards and US soldiers with just months of experience. The report calls for reducing the number of nuclear weapons in Europe to “reduce vulnerabilities at overseas locations.” The report was leaked to the Federation of American Scientists and published on its website. Hans Kristensen of the Federation of American Scientists said, “The main implication of the…report is that the nuclear weapons deployment in Europe is, and has been for the past decade, a security risk.”
