Agreed. Bibi’s aides should have persuaded him not to have come.
On the other hand, maybe Bibi thought that his speech at AIPAC and the warm welcome he received from Republicans and Congress would have shown Obama the level of support he (Netanyahu) enjoys in the United States.
Bibi is a true leader. He had to come and face evil even if he personally doesn't want to. By contrast, Obama, a false prophet, will always shy away from anything that he can't control.
