I personally don't think either A'jad or Erdogan are in this to just 'gain popularity' in the Muslim world.
Iran is threatning Israel for 30 years but they did not sent
single soldiers so far. Hell, even Cuba sent some soldiers, but not Iran.
What to make of Pakistan which is neither Arab, nor Persian, nor Turkish but still has maintained a very pro-Palestinian stance? Are Pakistani leaders too out to gain 'popularity' then?
I dont see Pakistani leaders making special statements about Israel, they just maintain the status quo.
There is even a theory--and one of Haaretz columnist has admitted in an op-ed--that Saudi Arabia may lure Israel into attacking Iran only to bite Israel's a$$ in the process.
Saudis hate both Israel and Iran, so war between Israel and Iran is their wet dream.
You need to study the secret alliances which were in place before WW I broke out--the killing of the Archduke only made them materialize.
I dont know about the secret aliances. Triple Entente and German - Ottoman were pretty open aliances before the war.
Israel has very little room for miscalculations. Israel simply cannot win with or without Western aid if Turkey joins an Arab-Iran war against Israel. Those nukes are the weapons of mutual suicide at best.
Its so wrong for so many reasons, I dont know even where to start. I'll list just some:
* Supplying armor divisions many hundreds miles away is logistic nightmare. Only US can afford these enormous spends.
* Israel has 12 divisions, its simply impossible to collect and supply some 20 divisions to make successful offensive against them.
* Actually you cant pack more than 3 divisions on Golan heights, so numerical advantage even if it existed, wont give much.
* Turkey has absolutely no experience in tank battles, Irans record is very poor (they tried to capture Basra for 6 years, and failed, while US took it in 3 days).
* Turkey has very few modern tanks, Iran does not have them at all.
* Wast majorty of Turkish officers are secular, dont see them willing to die for Arabs, actually non secular Turks either. Dont see Persians whos fathers were killed by the Arabs dying for them as well.
* Turkey has fast developing economy, last thing they need is destroying it for absolutely unnecessary war.
So nothing will happen, especially since Iran's experience show that you can gain lots of popularity without doing anything. Just by talking.
