It's very doubtful the US will bomb Egypt over that, it didn't even bomb Egypt when it was directly involved in wars with Israel. Currently the Egyptians are in violations of the peace agreements with Israel over stationing military forces in Sinai, yet no bombs are falling.
Generally I think they targeted the US because of Islamist Ideology.
Islamism links conquest and imperialism to a proof of the religious validity of Islam.
Once the West has begun its control over Arab countries the idea in the 1920s has emerged where the reason why Islam lost its prominence is because they lost the "true" islam. Therefore the solution is to return to medieval Islam, similarly to fascism nostalgia to the Roman/German empires.
In that context, even the fact that the United States exists as a cultural force and influences arab teens to wear jeans is a major threat. Don't be naive that it is all over Palestine, Islamism started prior to the existence of Israel.

You don't have to speculate. You can actually just look at what the bombers stated the purpose of their attack was. It wasn't part of a conquest; it was an attempt to punish us for our history in that region, with a very specific policy of ours mentioned explicitly by many of the masterminds of 9/11.
The only Islamist movement seeking conquest in recent history was ISIS, which is why a lot of their attention was spent expanding their caliphate into their neighbors' territories rather than launching quixotic attacks at the US on our soil. I'm not including ISIS-K in this assessment, as they glow more than Langley.
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.
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.
