Well, you're instincts are correct. The Arab nationalist parties and the Nazi party both grew out of dissatisfaction with the WWI settlement, economic depression, anti-West and particularly anti-British sentiment, as well as anti-Semitism. Arab nationalist groups modeled themselves after the Brownshirts. Sadat was arrested by the British as a Nazi sympathiser. The leader of the Palestinians in the 1940's, the Grand Mufti of Jerusalem, traveled to Germany to meet Hitler, expressing admiration for his policies toward the Jews. At the beginning of WWII pro-Nazi regimes had to be overthrown in Iraq and Syria. After the war, the Arab nationalist (fascist) parties seized control of Iraq, Syria and Egypt, resuming their authoritarianism and virulent anti-Semitism, gradually transferring their hatred of the British to the U.S.
Iran pioneered grafting Islamicism onto Arab fascism. Al Qaeda did the same on the Sunni side, grafting radical Wahabbism onto Arab fascism. Although Saddam Hussein is an old fashioned fascist, since the time of the Gulf War he has pretended to be an Islamist to save his skin.
We are up against radical Islamic fascism. The "peace movement" in the West, composed mainly of "useful idiots" of the Left, have no idea what they are supporting.
