I have never heard of that "agreement", has anybody else? Here we have an Israeli journalist claiming that Turkey has violated "the tripartite agreement between Israel, the United States and Turkey". As far as I know Turkey is a sovereign country and a member of NATO and have never sign a "tripartite agreement" with the US and Israel. As for the cancelation of "international participation" in the upcoming drill on the Anatolian plateau, well it was to have including "practicing aerial attacks in Turkish airspace near borders with Syria, Iraq and Iran" and with the Turkish PM preparing his upcoming visit to Tehran, it just wouldn't have looked good. The cooling of relations between the two countries has been ongoing with various incidents, but the snub of the Turkish Foreign Minister's request to visit Gaza was the last straw that broke the turkish camel's back. Now back to ficticious "tripartite agreement", has anybody ever heard of such "agreement"?
