The Court considers that the military exigencies contemplated by these texts [the 4th Geneva Convention and the 1907 Hague Regulations] may be invoked in occupied territories even after the general close of the military operations that led to their occupation. However, on the material before it, the Court is not convinced that the destructions carried out contrary to the prohibition in Article 53 of the Fourth Geneva Convention were rendered absolutely necessary by military operations.
What exactly would convince them of the "absolute necessity" of Israel's military situation? Maybe a couple 100 more suicide bombings will have them come to their senses.

A side note: Am I the only one amused to hear that the opinion in the case was written by a Chinese Justice? Because its not like the Chinese have ever experimented with putting up a big wall to keep out invaders and barbarians.
