As Benjamin Netanyahu began his latest visit to Washington, DC, to reaffirm Israel’s indispensable alliance with the United States, a public opinion survey offered a remarkable measure of how profoundly that relationship has changed.

His greatest strategic failure was political. By tethering Israel ever more tightly to one US party, treating Republicans as permanent guarantors while dismissing Democratic concerns, he undermined the broad bipartisan consensus that had anchored the relationship for decades.
