Surely, when we are critical of a nation's government, we are not condemning all the people governed by it?
The West is at loggerheads with Iran (for example) - are we reviling its people, many of whom appear also to be opposed to its own government? Are we censuring Islam because we denounce an administration that has appropriated the religion for its own ends?
Even within governments, there are factions that disagree, we've seen it with our own government.
Are we then to keep quiet, not question, not hold governments accountable?
Azhar Ali was wrong to say that Israel planned to "get rid of [Palestinians] from Gaza" and "grab" some of the land - because he is presenting it as a fact, and as far as I know has offered no evidence to support it. If you are in the 'public eye' you cannot make inflammatory statements like that and not be held accountable, and the Labour Party should have withdrawn its support for him as a candidate immediately.
In the interests of free-speech and Democracy, one can still ask the question though of why - if the Israeli government was made aware of the intelligence that indicated Hamas might be planning an attack (and such intelligence allegedly came from more than one source) - they appeared to ignore it. Surely those whose family members were slaughtered so barbarically in the attack have a right to know and will want to know if it could have been prevented? Governments have a duty to protect their citizens - as far as is possible anyway.
