Troll - Without its dominant military/political/economic system in the world, I don't think the USA would presently have those troops in Saudia Arabia, nor have the Saudi government in their pocket. Highly doubtful. So yeah, I think you may have missed what is implicitly obvious in Bin Laden's writings.

When Britain was the dominant world power, it had troops in many far flung places too. If Bin Laden were living in the 1800's he might well be besieging Kartoum or participating in the Indian Mutiny, throwing the Sahibs and Memsahibs in the Black Hole of Calcutta...or defending the Kyber Pass against a British column.

So it goes...
