"If, as seems likely, Binyamin Netanyahu and the Likud Party wins the election next Tuesday, this will be a real test. Netanyahu will have to build a coalition to govern--does he include Yisrael Beitanu?...If Netanyahu goes the radical route, it has to be seen as an extremely provocative, xenophobic (and perhaps racist) move. The U.S. should express deep concern and disapproval."
Klein is right to be concerned, but this sentiment is far from new. Commentators and politicians in Israel and the U.S. have been worrying about a possible Bibi-Lieberman right-wing all-star team for quite some time now.
However, what's even more noteworthy than Lieberman's acceptance among Likud leaders is his acceptance among the leaders of the other two major parties. Today, Kadima's Tzipi Livni proclaimed that Lieberman is a viable coalition partner, and Labor's Ehud Barak, despite complaints from party members, has said the same. (They both included the caveat that Lieberman must adhere to their party's principles in any coalition government. Good luck.)
Bibi's potential coalition with Lieberman was never too surprising. That both Livni and Barak have deemed it potentially acceptable, however, shows Yisrael Beiteinu's established and growing power.
