Even I think we have no right to be throwing our weight around in the middle east and that our support is Israel is pretty one sided. Why wouldn't bin Laden feel even stronger about it?
There is no logical reason for the claim that "bin Laden doesn't really care about those policies"
It just doesn't make sense that bin Laden doesn't actually object to the specific foreign policies that he complains about, millions and millions of other people object to the same policies, by what "logic" would it be that bin Laden would be in a extremely small minority that "doesn't care" about the policies or thinks they are fine?
There is no evidence that bin Laden isn't actually angered by the specific foreign policies he complains about. In fact he has repeatedly stated the motives through the years and so have others.
"... the Mujahideen saw the black gang of thugs in the White House hiding the Truth, and their stupid and foolish leader, who is elected and supported by his people, denying reality and proclaiming that we (the Mujahideen) were striking them because we were jealous of them (the Americans), whereas the reality is that we are striking them because of their evil and injustice in the whole of the Islamic World, especially in Iraq and Palestine and their occupation of the Land of the Two Holy Sanctuaries." -Osama Bin Laden , February 14 , 2003
in that same statement Osama bin Laden once again listed the motives: " ... in 1995 , the explosion in Riyadh took place, killing four Americans, in a clear message from the people of that region displaying their rejection and opposition to the American policy of bankrolling the Jews and occupying the Land of the Two Holy Sanctuaries. The following year, another explosion in Al-Khobar killed 19 Americans and wounded more than 400 of them, prompting them to move their bases from the cities to the desert . Then in 1998 , the Mujahideen warned America to cease their support to the Jews and to leave the Land of the Two Holy Sanctuaries, but the enemy refused to heed this warning, so the Mujahideen, with the ability from Allah , smashed them with two mighty smashes in East Africa . Then again America was warned, but she refused to pay attention to the warnings, so the Mujahideen destroyed the American Destroyer, the USS Cole, in Aden, in a martyrdom operation, striking a solid blow to the face of the American military and at the same time, exposing the Yemeni Government as American agents, similar to all the countries in the region." -Osama bin Laden February 14, 2003
