"When two countries participate together in military action, according to Turkey's constitution that has to be approved by the Turkish parliament," said Aydin.
"At the present time it is unclear whether France is acting in the framework of the international agreement among the countries of the Alliance, or its forces are in Turkish airspace at Turkey's request, as was the case with the deployment of Patriot air defense systems in Turkish territory."
"This issue has to be investigated, in order to find out whether the Turkish-French agreement is in accordance with the norms of constitutional law," said Aydin, a former constitutional court judge.
Turkey's geographical position gives it a favorable place in the alliance, and being able to use its airspace for airstrikes is in keeping with NATO's strategy of extending its presence further into Turkish territory, despite links between Turkish officials and jihadi terrorists.
That process began with the opening of the Incirlik air base to the US air force, and continued with the deployment of Patriot missile-defense batteries, and with the scheme to train and arm opposition groups in Syria, said Aydin.
"The opening of Turkish airspace to French aircraft can be called an attempt to relieve a certain pressure inside NATO, and give an answer to Russia's political and military maneuvers in Syria," said the expert.
"This strategy of the alliance is above all linked to the desire to gain benefit from military action, to establish new forms of cooperation between NATO members."
"France and Turkey are two countries which, in a very short space of time, suffered terrorist attacks in their capitals, and have been chosen for this role," said Aydin.
How lovely to see Turkey so tenderly protective of the law...
