The issue is not whether Israel signed things or not, though it's incredibly buttock-clenching to read about how the US have let Israel off the hook in this regard in such a lily-livered way. Truly, the US is Israel's poodle. The issue is that Israel is in breach of a treaty that its major aid donors subscribe to, and that those donors daren't say anything really. Mainly thanks to the undemocratic pro-Israel lobby, led by AIPAC, which, in the land of the free, dictates absolutely what politicians can and can't say about Israel. Now stop pissing around and let's hear you deny that.
