Lawrence Wilkerson is a creature of the State Department, but even he understands that - regardless of military strategy - Israel and the US are in this together:

Look at it this way: if Israel was physically overrun or destroyed by militant Islam - Israel, which is considered by the enemy to be a Western foothold in the ummah - do you think it would encourage or discourage radical forces? It's the diplomats' game to avoid actions that encourage radicalism - do you think that radicalism would be more or less popular when it thinks that it's streamrolling over the West? Do you think the organization or state that destroyed Israel would get more or less recruits? More or less funding?

This is so painfully obvious - and, frankly, irrefutable - that we can't imagine that any reasoning person could deny it. Which is why we suspect that at least among people who've thought about this a lot, there might be a hint of something other than rationality driving things.
