Turkmenistan!

From Eurasianet:

Israel has announced it will open an embassy in Turkmenistan’s capital of Ashgabat, located just 32 kilometers from the Iranian border.

Foreign Minister Avigdor Lieberman held a series of "secret talks" with officials in Ashgabat and a team of Israeli diplomats and security personnel will visit the Turkmen capital later in May to select a "suitable building" to house the Israeli diplomatic mission, Israel National News reported May 13.

Turkmenistan and Israel established formal diplomatic relations 17 years ago, but to date no Israeli ambassador has resided in the Central Asian state.

Ashgabat is situated in the foothills of the Kopet-Dag mountain range and is just a short drive from the Bajgiran border point. Turkmenistan and Iran share a 994-kilometer long border.

Even if Israel/Turkmenistan cooperation never reaches the point where this is strategically important, just knowing how much it ticks off Iran - that a neighboring Muslim state would open an embassy of the hated Zionists - makes it all worth it.
