EB,
There is a Yang to that Yin ( Thank You Slycoordinator).
Obama also was playing politcs sandbagging Bibi.. so it cut both ways. Obama was playing to his far left base.
for Bibi, right now he doesnt have the votes in the knessett to do much anyway, he cant concede land if he wanted to.
I personally dont thing Bibi came to DC to have this even be a subject, Carney said Obama was not going to talk about the 67 borders 24 hours before Obama sandbagged Bibi, so I dont think Bibi did anything but react defesively to Obamas hostility. Bibi didnt have time to really think it out and go with a plan., maybe it worked for him anyway..
