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.
Criticism of United States foreign policy
The U.S. is advocating that Iran and North Korea should not develop nuclear weapons, while the U.S., the only country to have used nuclear weapons in warfare, maintains a nuclear arsenal of 5,113 warheads. However, this double standard is legitimated by the Nuclear Non-Proliferation Treaty (NPT), to which Iran is a party.
