Nuclear triad
Israel is known to have nuclear-capable aircraft and land-base missiles, with the addition of nuclear-armed submarines this would mean that they now have a full triad of land-, air-, and sea-based nuclear delivery systems some of which would be invulnerable to a first strike by an enemy for the first time in their country's history. No other nation in the Middle East in known to be in possession of nuclear weapons, even though Iran, Iraq, Syria and Libya have started development programs that were never completed.
Kleine Brogel Air Base
None of the five NATO member states, whose air forces allegedly might share in its premises nuclear bombs with the USAF (these are Belgium, Germany, Italy, the Netherlands and Turkey), have ever provided an official confirmation of its existence. However, former Italian President Francesco Cossiga declared that the Aeronautica Militare hosted or shared American nuclear bombs, just as other NATO member states do. In an interview he talked about French weapons. In the same way, on 10 June 2013, former Dutch prime minister Ruud Lubbers confirmed the existence of 22 shared nuclear bombs at Volkel Air Base.
