This is apparently the last cartoon 'tweeted' by the French magazine "Charlie Hebdo" before the murderous attack on their offices. It is apparently the leader of "Isis". It looks pretty staid to me. Compare it to other cartoons of other people in the past.
A blood stained Hitler or General Togo as a grinning semi-monkey.
Or even an insect.
The 'offensive anti-muslim' cartoon pales into insignificance by comparison to these WW2 allied cartoons. And there is the point often missed. It is not the cartoon which is the cause of offence but the fact that the writer / artist is disagreeing with Islam.
But whatever the reason or cause of the mass murder in Paris we support freedom of speech and publish the last cartoon tweeted by "Charlie Hebdo" as a mark of solidarity and respect for the victims of the killers.
