Proportionate doesn't mean what you say it does. Pal falafel stand bombing would be exactly proportionate. Pals are so much against suicide bombing as the Germans were against the SS. Even less,streets of pal towns are adorned with pictures of their 72 virgin shaheeds,Germans kept the identity of their SS-murderers secret. So Peretz and your assertions are a politicallky correct rubbish. p.s. Yassin's killing proved exactly the same reacions from the EU,"Inacceptable!!",so much for hitting the perps only.
