Yeah, that's just whataboutism.

Edit: To elaborate, because there was another comment comparing this to Assad in Syria:

I think the difference is that Assad already belonged to the "enemy" is of the West (rightly so) and was immediately hit with sanctions.

What is special about Israel is that the government and, as it seems, large parts of the population, are displaying the same mentality - but unlike with Assad, no one is putting on the brakes here or threatening sanctions. On the contrary, our governments are protecting and enabling Israel in its behavior.

I think the aggression specifically towards Israel stems from the feeling of being on the wrong side this time.
