Amnesty international has published a report on their opinion that Hezbollah did commit war crimes. For some reason it took them longer to reach such conclusion than to conclude immediately, spontaneously and incorrectly that Israel has committed war crimes.
A very good piece on the subject of their bias was written by Harvard law professor Alan Dershowitz. Read here.
The mere fact is that this is not the first time they do this; they cling to every bogus claim of victim hood by Taquiyya committing Jihadists. They are quick to accuse Jews and Israel of horrific crimes, then after years of such behavior, and after dozens of one sided reports they wash their hands by a single short and very quietly published paper admitting that what Arabs are doing to Jews is without a doubt a war crime. Only after 9/11 did we see them go after the US with similar impertinence while trying to tag every measure taken to defend Americans as violations of human rights. Violation of the rights of the terrorists.
They are Anti-Semite by their actions. Their bias and zeal to indict Jews first cannot be interpreted by anything but Anti-Semitism however much they will deny it.
