While attention toward Iran has focused on the failing nuclear talks, Tehran has been ramping up a renewed territorial claim that threatens serious long-term instability in the Persian Gulf. In recent weeks, Iranian media have been reviving claims that Bahrain, a key US ally, is the “14th province” of Iran, known as "Mishmahig".

History shows Iran’s demand is baseless. In November 1957, Tehran declared it a province. However, after heavy British and US pressure and a United Nations survey showing overwhelming public support in Bahrain for independence, in 1971 Iran recognized the island nation as a sovereign state.
