In February of 1958 Egypt and Syria merged into the United Arab Republic in an effort to further the Pan-Arab movement. A 1961 coup in Syria threatened the Union, following negotiations with the Syrian officers the union was reinstated. UAR President Nasser later supported the Pan-Arab rebels in Lebanon which resulted in Lebanon joining the UAR in 1959. After the assasination of Iraqi Prime Minister Abd al-Karim Qasim in 1963, Iraq sought and gained membership into the UAR. In 1965 Libya sought membership into the UAR due to the growing popularity of Arab nationalism in the nation. As of 1965 Sudan, Palestine, and North Yemen are seeking membership.
Why Jordany want not to join?
Jordan and Iraq (pre-Officer's revolt) were fiercely against Nasser's PanArabism.
Yeeeeahh nice Finally a new map from you <3
How does the Six Day War factor into this?
This is set before the Six Day War.
I know, I was asking how the Six Day War would go in this world.
Sorry, I misunderstood. I honestly haven't considered it, I don't tend to think too far past a scenario I have in my head. How do you see the war going in this world?
Well, if the same preemptive strike scenario plays out with Israel, but you've got a larger part of the Arab world backing the UAR, then the Six Day War might be something closer to the Two Week War, which might still be a victory for Israel and what might still be a great Sabaton song, depending on how well organized the UAR's military is (given how rapidly it's expanding and absorbing different nations, I'm guessing not very organized at the moment).
