Wow, this belongs more in the Conspiracy Theory section than in the Military section.
A newspaper that is known for fabricating articles did a what-if calling for all Arab nations to attack Israel? And you take this to mean that the President of Turkey is calling for that? Insanity at the extreme.
To begin with, even if the President tried it, the Army will simply overthrow him in another coup. The Army there has a rather long tradition of staging coups if the leadership gets out of hand, and returning power back to the Parliament.
And it is doubtful that such a call to arms would get much traction among the other Arab nations. Jordan, Saudi Arabia, and Egypt all have formal peace treaties with Israel, and maintain at least some levels of cooperation with the goal of regional stability.
And with the US presence in UAE, Bahrain, Qatar and Kuwait, it is unlikely that any of them would participate either. All have become dependent upon US aid in keeping Iran from trying to enforce territorial claims and Finlandization against these smaller nations.
That leaves really only Syria, Iraq, and Lebanon to assist a theoretical Turkish invasion. Not likely to happen.
Remember, Yeni Şafak is the paper that printed a completely fabricated interview with Noam Chomsky, even go so far as changing comments that Mr. Chomsky made critical of President Erdogan and turning it into support for him. And during the 2013-2014 Protests in Turkey, they portrayed the protestors as Apostates who were drinking alcohol in mosques and attacking women on trains. They claimed to have video of all of these incidents, which somehow was never produced (and video acquired form independent sources showed nothing that had been claimed).
This "newspaper" has been shown to have fabricated dozens of reports over the last decade. And this is your source?
Might as well try to claim that your source is the Weekly World News. I think it had more credibility.
