Too much of a good thing?

Is it possible that us diaspora fans of Zion are loving Israel too much. Daniel Levy writes in Haaretz about the new John Mearsheimer and Stephen Walt study of "The Israel Lobby and U.S. Foreign Policy." He says:

It should serve as a wake-up call, on both sides of the ocean. The bottom line might read as follows: that defending the occupation has done to the American pro-Israel community what living as an occupier has done to Israel - muddied both its moral compass and its rational self-interest compass.

Interesting food for thought. Has our love of Israel blinded us to Isiah’s vision expressed in the Jerusalem program of building a nation based on the prophetic vision of righteousness and peace(justice).
