Your link to the book by Benny Morris does not state what you claim -yes, some Moroccans went to Egypt to fight Israel, but as Morris points out, they never got there, being deported because they were 'restive and argumentative' (page 85).
This source confirms that Morocco did not participate in the War of 1948
"In contrast to the Arab consensus, Morocco, which was not independent in 1948 and did not take part in the War of Independence, established clandestine relations with Israel."

I don't see any contradiction in what I wrote. After Suez, Nasser accepted arms and support from the USSR, it was part of the Cold War in the region, but while there had been a Communist Presence (the CP of Palestine was formed in 1923, the party in Iraq was formed in 1934) Arab Nationalism was the dominant position of most of the frontline states, not so much the Arabian Emirates and Saudi Arabia.
Suez far from being a disaster marked the rise of Nasser, and was the basis on which he not only attempted to expand Egypt's influence in the Arab world, but also the means whereby he crushed the Muslim Brotherhood at the time -such as the execution of Sayid Qutb in 1966. For some people, the assassination of Anwar Sadat, a close associate of Nasser, was as much about the Nationalist crushing of the Brotherhood in the 1950s and 1960s as it was the 1979 Peace Treaty with Israel.
Nasser's ascendancy was thus fundamental to the overthrow of the 'Imamate' in Yemen in 1962, and the war with Saudi Arabia that followed. And it was because Egypt was seen as a client of the USSR that the US sent arms through Israel to the Saudi backed forces who were as useless then as they are now. The war dragged on until 1970, the Imams never regained power. Yemen split into two countries, and is broadly speaking one of the most ungovernable places in the world.
Once again, you are entitled to your opinions, whether they are based on facts, conjecture, or just some weird idea you have of what happened, but I do think a little more reading would help, and you don't need Wikipedia, which I agree can sometimes be unreliable. I am sure that even in your country there are libraries which have books, in fact I am certain of it.
