Possibly, and the Saudis are pumping hot air in the Northern Thunder drill:
There will be 21 Arab and Muslim countries taking part in huge drills,” Assiri told London-based newspaper Al Sharq Al Awsat. “It will serve to boost fighting capabilities, exchange information, benefit from experiences and expertise and enhance coordination between the participating countries. There will be joint military command centres,†he said.
Assiri added that “when participating countries feel that there are coordinated and interdependent efforts, the results of the exercise will be positive. We have models based on real experience of being in the Arab coalition in Yemen where operations are running excellently and positively,” he was quoted by the daily as saying.
Patriarch Kirill also said that the preparation process was continued in preparatory commissions and at the 4th Pan-Orthodox Pre-Council Conference in 2009. “In March 2014, I took part in the Meeting of the Primates of Local Orthodox Churches which took place in Istanbul. It made the decision to convene a Pan-Orthodox Council in 2016, “if unforeseen circumstances do not prevent it,” His Holiness noted.
