I am only not more directly critical of the Administration's response as there are indications that they are working to (and maybe a having some, though far from enough success) moderate Israel's actions (delaying a ground invasion, among other things), and cannot discount the possibility that a better rhetorical position would have worse substantive results.

At the same time... I don't disagree with any of your characterization of the problems with the positioning of the Administration, outside of that consideration.
