The editors have laid out the fundamentals of what's wrong with Majority Leader John Boehner's invitation to PM Benjaming Netanyahu to speak to Congress. And this post from January 21 links to early commentary on Why and How this happened.
Since then, there have been reams of analysis. Among the most diverting, those suggesting that there are no strategic national differences between the U.S. and Israel even if Israel wants to bomb Iran and the U.S. does not. Rather it is just personal or political or something.
Two example of that commentary:
The Bad Marriage metaphor in which the bad relations between Obama and Netanyahu are said to lie at the heart of the controversy. Here from DC and Jerusalem is that analysis by Times' reporters Peter Baker and Jodi Rudoren.
The second is an analysis arguing that the famous "bipartisan" support for Israel no longer exists. Bernard Avishai writes in the New Yorker: In "Netanyahu and the Republicans," he argues that the Republicans and Likkud are now aligned. How will the Dems take that?
