In the long term, the US is not going to be able to get pro-US dictatorships over the entire Muslim world. Without pro-US dictatorships, the US cannot get governments that will adopt cooperative policies in the supposed "war on terror". Therefore the US will lose the Global War over the Legitimacy of Israel.
I doubt the US will ever successfully get even one more pro-US dictatorship than there is already.
- No pro-US dictatorship for Pakistan, (Musharraf having to become less pro-US for domestic reasons). The death of Bhutto emphatically marks the end of that dream.
- None for Palestine (pressure is already building for Abbas to accept Hamas in a unity gov't). The Arabs that the US needs to isolate Hamas are just not willing to do that.
- None for Lebanon.
- None for Iraq (Iranian-supported parties will at least be a stakeholder in the country, preventing the US from imposing a dictator who can go against Iraqi wishes on foreign policy)
- None for Iran (of course regime change is way way way off the table by now)
So since a loss is nearly certain in the long run, it is only a matter of time before US political class understands the impossibility of its global war and withdraws. The US will say in different words: "OK, we cannot convince you to accept leaderships friendly or even tolerant with Israel. What policies would the US have to pursue for you to accept leaderships friendly or at least tolerant of the US?"
This will be seen in Israel, accurately, as a spectacular betrayal or at least abandonment.
Unfortunately, the realization and withdrawal will not be this election cycle, even though some candidates, even a one-time front-runner, seem to see the writing on the wall.
