Turkey, with its present pro-Islamic party, will naturally care about the Palestinians. However, i think there is more to this case than just simple 'muslim helping muslim'. I think it has become a matter of prestige too for Turkey, Iran and the Arab world to see which one will be the loudest anti-Israel and leading player in the Islamic world. Doesn't mean that Israel is not without its own mistakes though, it must face all consequences, but i just find it funny how that country is targeted while there are many other countries in the world where muslims are facing problems, yet they almost go unnoticed by the muslim world, it seems. It's Erdogan's strategy to reach out more to the Arab world (what you called neo-Ottomanism), which also shouldn't be neglected due humanitary help, but imo it would be wiser to not stick our nose too deep and surpass the point of no return in this matter and focus more on our own, Turkic, world.
Exactly right.
