Either you are biased or you don't know much about Gaza and Israel, and their history. Israel does not need money from whoever. Most people in Gaza support Hamas, a terrorist organzation. To any civilized humzn being, they are barbaric - as are all Jihadi everywhere.
Personally, I don't think it's so much the right of Israel to defend herself as the need to eliminate a terrorist organisation sitting on her doorstep.
Why doesn't the first world 'do something' about Israel? Because we are all disgusted by the continuous barbarism of Jihadi internatiinally. Pro-Palestinians can make all the noise they like - in the west one is allowed to make a noise.
That's about it.
In reality, nobody approves of the barbarism of the Jihadi.
