And you should not make such comments about knowledge of history lessons to others brother. May be they have read a few words as well.
BTW Geopolitics cannot be related to history as simple as that. The era in Which you are talking about Arab Israel war was the same era when East and West Germany were Sworn enemies of each other, And Iran was Ruled by a Shah who was as close ally of Pakistan as turkey and China are today. And Shah Government was very close to Israel even they Co-developed Weapons together. their was a Mighty Iraq in the Middle East and a lot of factors.
I sense you are viewing this conflict with sectarian view. In that case i am not going to argue, every one is capable of his own view.
BTW the Real Problem with Iran Syria is that Iran wants access to the Strategic ports of Syria in Mediterranean sea for its Business Interests Primarily and to a lesser extent Direct Border Access to Israel to Threat it directly as it cannot match Israel in Strategic long range Strikes. And its problem with Israel is the legitimacy of its regime stands solely upon the concept of being bulwark of Islamic Resistance against Western influenced world (which clearly its not). If it stops to pursue this, it looses its total Legitimacy of being a revolutionary Islamic republic to its people and to the Muslims who support it. (Even they are starving their people while achieving this and the whole concept of this being valid or not is another discussion)
Current Baathist Syria is the only remnant of the Old Pan Arab Nationalist States who fought the Pro-Arab war against the Jewish Intruders. that was led by Gamal Abdul Nasser and the only surviving Baath State. They are a sort of Political Rivals to Israel state, Bashar is son of Hafiz ul Assad who was primary member of Nexus of Nassir-Qadaf-Hafiz. (BTW all Anti Israel that actually Attacked Israel were Secular Pro-Soviet Union States non of them was any way near Islamic not even as close as us)
And it doesn't matter if these Arab Countries are democracies or not. All Arab Coalition governments that Fought against Israel were non-Democracies.
Also the Democracy of Egypt was largely removed by Support of Saudi Arabia and Syria as it was Muslim Brotherhood government and MB does not stand good with a lot of regional Arab Governments, Only Turkey supports MB. KSA, Jordan, Syria, Iran all of them hates MB. But that's a topic of another time.
Egypt chickened out of Israel Conflict to get its Sinai Peninsula back from Israel (Which was under occupation of ISrael) under the leadership of same Anwar Sadaat that Fought a war against Israel and to date Egypt Blockades Ghaza Strip.
Hafiz ul Asad refuse such Peace with Israel as secret negotiations to hand over Occupied Golan Hights failed as Israel was willing to give away only a part of it and not full. (Golan is Syrian territory occupied by Israel).
And as for Jordan and KSA, They don't need to mess with Israel. They are happy as they are and don't have a legitimacy-identity crisis Like Iran.
At the end of the day, no Muslim Country is Strong or Willing enough to genuinely counter Israel State mate, Everyone is doing topi drama.
And the Wars against Israel by Arabs were Pathetic, Read them in detail with neutrality. Even Pakistan did better in 1971 compared to these 3:1 outnumbering Arab Armies being beaten to death and outmaneuvered by Israel. If we can fend of a 7 times larger enemy, they should also learn to fight for their lands against a 7 times smaller enemy
