I don't need to speculate, I can read the ideological foundations behind the Muslim Brotherhood, Salafism, the Islamic Republic etc.

One part is rejection of modernism and romanticism of a fantastic past similar to fascist movements. Other is anti-colonialism, but only in the context of european colonialism, not muslim colonialism, which is fine. Because of the aforementioned romanticism to the middle ages, part of any Islamist project is creating a Caliphate, and it is easy to see in Islamic history that these were boundless.

The reason Palestine may be important for them is that according to their perception, while european colonialism is a humiliation, there is no greater shame than the existence of Israel, as it is no some vast British Empire, but rather a nation built by refugees and therefore weak by definition, thereby enhancing their defeat, which in their mind has religious implications. As Islam is a conquering religion, and their conquests are a proof of Allah's power.

That's still speculation.

>The reason Palestine may be important for them

When I said they did 9/11 over US support of Israel, I didn't mean that they did it because of Israel's occupation of Palestine. They did it because Israel is the inventor of modern terrorism (Lehi and Irgun, the head of the latter was even an Israel PM!) and has terrorized every single surrounding nation since its invention by the British over a century ago.
