In an attempt to bolster its leadership role in the Arab world, Turkey has recently done almost everything it could to alienate Israel, to the extent that neither currently has an ambassador in the other's country. Turkey also decided to cut off all government-based business deals with Israel – ending a formerly substantial trade in military equipment, including, according to Defense News, unmanned aerial vehicles (UAVs); according to the publication, Turkey purchased 10 Heron UAVs from Israel Aircraft Industries in 2010. No more such purchases are likely.
