The blockade was set up by Olmert/Livni, and it is now Livni who is opposed to loosening it. So why would Livni be of use in dealing with the Gaza problem? Would the war crimes charges against her be dropped if she joined the coalition? And the blockade policy reversal isn't against right wing or even religious ideology. The Torah actually says that when you besiege a town, you should leave one border open - surprise! It also says not to destroy fruit bearing trees (or coriander fields). Netanyahu understands reality. Blocking food and luxury goods for civilains does not help Israel's case; it hasnt stopped kassams and has not freed Shalit.
