When they are not being accidentally carried over US cities, the movements of the US nuclear arsenal are top secret but the USA have been kind enough to remove its nukes from Britain after the last 110 American nuclear weapons left in the UK were quietly removed from RAF Lakenhealth in Suffolk.
At a time when the United States are applying pressure on Iran over its nuclear ambitions, the US still has nuclear bombs in five European bases, in Belgium, Germany, Holland, Italy and Turkey although the issue is controversial and continually draws protests as has the new idea of placing US interceptor missiles somewhere in Eastern Europe.
A 2006 Greenpeace Survey showed that 70 percent of Europeans want to live in a nuclear weapons free Europe. The polling data also demonstrated that a sizable majority of the citizens in countries which host US nuclear weapons were unaware of their presence.
With the overwhelming response on finding out another country holds such devastating weapons in your country being to tell them to get them the hell off, the governments of several NATO countries have insisted that these weapons be removed from their territory. The US has previously removed their weapons from Canada, Greece, Greenland and Iceland who are all now free of US nuclear bombs.
Britain and France are the only nations in Europe with its own nuclear weapons although Britain is not averse to stashing its devastating armaments in other countries, during the cold war it hid nuclear weapons in Cyprus and Singapore without even telling the respective host Governments.
What this all means is that England is now free of nuclear weapons. All of our own nuclear warheads, missiles and submarines are stationed in Faslane, Scotland which will be well received this side of Hadrian's Wall and suits me as i live on the South Coast of England and as far away from them as is geographically possible, but ensures that our (Scottish) Prime Minister is not going to win any popularity contests up there anytime soon.
