It believes apparently it alone can flaunt international law and the world can do nothing about it. Besides, it has the U.S. as its prime apologist, enabler and staunch defender over anything the Israeli government decides, so the rest of the world can go to--well not so fast.
Israel can no longer hide behind the horror of the holocaust and ignore its own cruel and inhumane occupation of the Palestinians.
This was not the intention of the world in 1948 when it chose to grant the reestablishment of the modern state of Israel.
Israel has let its orthodox Jewish minority exercise an outsized influence over governmental policy regarding the expansion of settlements, allowing the displacement of Palestinians from their land by mostly orthodox Jewish settlers (who openly despise the Palestinians, afford them no respect and dignity and see them as the enemy).
These orthodox Jews, apparently so beholden to their ancient beliefs i.e. the West Bank, Gaza, Jerusalem et.al are all a part of greater Israel and the Palestinians have no rights there, that Jews have the right to "reclaim" these lands as their own (supposedly granted by God himself) are beliefs that can not be reconciled with the reality of the world as it exists i.e. Palestinians have inhabited these lands for more than a millennium, legally own and reside on them and it is an indefensible injustice to forcibly remove them.
The seizing of the humanitarian flotilla in international waters is a microcosm of Israel's hard line defensive reaction toward any challenge to its policies.
Israel's blockade of Gaza is considered legal only by the Israelis. The world thus far (prior to this incident) has acquiesced to its existence, choosing to ignore it, rather than challenging its legality. But Israel's actions in international waters are clearly illegal and the world has responded accordingly.
It is only the U.S. that has been muted in its response to this latest incident. This writer, in his initial response to the Israeli raid, ("Israeli Naval Action on the High Seas", OpEd News, June 1, 2010) wrote "Israel should not be given special dispensation by the U.S. when official findings clearly have them in the wrong."
Well official inquiries have been called for by the U.N. and the European Union. It is time for the U.S. to step up and join the international community and abide by the inquiry's findings.
The U.S. "special relationship" with Israel can no longer countenance Israeli malfeasance, if and when it is found culpable by legally authorized and impartial commissions.
We and the Israeli's must abide by international law. We and they are not above the law.
