Of course rockets have been fired. Israel closed off Gaza strip's borders even during the ceasefire starving the people to death. Also there is a large difference between Hamas and Palestinians as a whole. This is nothing more than Israel trying to make a case to gain back the Gaza strip. Then again when you've got a hammer everything looks like a nail.
Also did you know during the ceasefire Israeli soldiers killed 28 Palestinians. As for the reports of the rockets the figures are exaggerated. The proper estimate of rockets before the bombings was around 66. I don't care what's "left wing" or "right wing" a bias is a bias.
As for the support of Israel in western countries it's simply a matter of people trying not to piss off the Jewish people that live in the country. That'll make them lose votes, and nobody likes to lose votes. And yes I am saying that Jewish people are more inclined to support Israel than Palestine.
But I'm going to guess that you're going to say I'm misinformed, and that bombing innocent civilians in order to target a few extremists is acceptable. I'm not going to change your opinion, I just wanted to say in an educated way that you're full of shit.
