Then there was the Major General fired last March for groping "a female civilian employee while he had been drinking." But the most concerning incident was when an Air Force general in charge of nuclear weapons drank too much at official banquets, insulted his Russian hosts and hung out with two suspicious women he met at a hotel bar during a trip to Moscow in mid-2013. Nuclear scandal ... Maj Gen Michael Carey. Before he was fired last November, Major General Michael Carey was responsible for "maintaining and operating" three wings of the country's intercontinental ballistic missiles - 450 in all. According to the Air Force's official investigation, the Maj Gen also tried to perform with a band at a Moscow bar and one witness said he was so intoxicated at times, he was "concerned (he) needed assistance standing." He later described his unknown companions to US investigators as "hot women." They would not even tell him whether they were British or Russian. Deadliest weapons ...

Earlier this month, 34 Air Force officers responsible for nuclear weapons were suspended for cheating on monthly tests that assessed their knowledge of nuclear warheads. "The (revelations) are particularly alarming," The New York Times reported last week, because with nuclear weapons, "errors could be catastrophic." According to ArmsControl.org, the United States currently operates more than 5100 nuclear warheads. Even a "small" regional nuclear war where 50 warheads were launched could trigger a planetary nuclear winter lasting 10 years, a Rutgers University study said. The dangers to the country's arsenal aren't all internal, either. In 2012, a group of senior citizens including an elderly nun infiltrated at a nuclear weapons site at Oak Ridge, Tennessee. The facility "housed enough highly-enriched uranium to make hundreds of nuclear weapons," The Boston Globe noted. Anti-nuclear Sister Megan Rice, centre, is accused of breaking in to the Y-12 National Security Complex in Oak Ridge and painting slogans on the outside wall of its uranium processing plant. The nun, Sister Megan Rice, 83, will be sentenced for her crime tomorrow Australian time. Last week, the US defence chief, Chuck Hagel, ordered a full review of the nation's nuclear forces. He was blunt about what was happening. "Clearly, we've got some issues here," he said, while adding the nation's nuclear weapon arsenal was secure. Here's hoping he's right. Deadliest military ...
