Other than Human Rights Watch (featured in article) where is the condemnation from the west? Any other nation and all hell breaks loose. Iraq, Libya, Syria, Iran, Russia, China, but Israel and suddenly barbaric behaviour and breaking international law is fine.
Simply because Israel is in terms of the west 'friends/allies' and the other countries are our (the west's) perceived (historic) enemies.
Russia. The cold war. Nearly caused WW3 with the Cuban Missile Crisis.
Iraq, Iran, Libya, Syria. Terrorist attacks against the west, amongst other things
Libya. Lockerbie bombing, supplying Semtex to the IRA, amongst other things.
China. Simply because it's a ruthless dictatorship and has an extremely poor human rights record.
Another reason may be Israeli (Jewish) influence in the west, i.e. very prominent in politics, finance, media and the film industry.
Another reason may be the west wants to keep Israel on their side, not make an enemy of them and it could be crucial when WW3 breaks out (my prediction and most likely to originate from somewhere in the Middle East).
