Given what the US and allies (including us) did in Afghanistan after a handful of attacks, I can't see how we can criticize Israel for reacting like this to Gaza after not the worst atrocity they committed, but the years of attacks beforehand.
I really don't like Netenyahu. But even he isn't on the same level of evil as Hamas. Not that the leaders of Hamas are in Gaza any more of course - they provoked a predictable reaction then scarpered, leaving the poorer people to suffer the consequences.
I wish Israel would stop now - in fact I wish they'd stopped a long time ago. But the heaviest blame for the suffering in Gaza lies with Hamas.
Our government should be siding with the only country in the region which is a genuine democracy and gives its citizens decent rights, not with a group of people so violent that their Muslim allies and neighbours try to avoid letting them in.
