Well yes. Desperate people turn to deaperate means. In this case the people of Gaza turned to Hamas after years of suppression and murder by Israel. I don't condone what Hamas has done but Israel sealed it's own fate - it had a chance of peace with the PA and a two state solution. So equally I don't condone the murder of Palesinians by Israel. You were the one that stated there was no provocation - there was and continues to be. All Israel is doing is murdering innocents and in turn creating the next generation of terrorists - they really are that stupid !
Sorry, I can't call that legitimate provocation for what HAMAS and other terrorist groups have done. Probably my background of schooling near Washington University in St Louis, heavily Jewish school, has coloured my thinking but if your people had been almost wiped out by the dictators of the world including some of my kind of people in Germany you would think very differently too. You trust no one else to look out for your people.
