Yes, you missed that the bullets were aimed at specific parts of their bodies, so not just an assault on the ambulances: the medics seem to have been dragged out of the ambulances then deliberately shot in the head and heart, before being thrown in a mass grave. And at least one of them had had their hands and feet bound together before being shot in the head. This is a planned and deliberate execution of 15 medical professionals. Maybe the Israeli soldiers lined them up by the grave then shot them.

Ethnic cleansing is pretty popular in Israel:

80% of Israeli Jews support US President Trump’s proposal to ethnically cleanse Gaza, survey finds

The message is: don’t do business with the USA. Find other, more reliable trading partners. It may be a loss in the short term, but bowing to fascist imperialism and white supremacist ideology will be a much bigger loss overall.

Yes, it makes a lot of reasonable people antisemitic just because they can see what Israel is doing to Palestinians. Since the policy then can’t be enforced consistently, this kind of situation gives a government a pretext for punishing anyone they dislike for other reasons. It’s still useful to governments to have laws almost everyone breaks, and that are seldom enforced, because then they can choose when, and against whom, to enforce them.

Ah, of course, it’s not real antisemitism: it’s the kind where you say mass murder and genocide are just as bad when perpetrated by Israeli Jews as they are when carried out by anyone else. And this seems to be part of a worldwide trend that goes along with the lurch toward fascism, for governments to decide they can kick out and disown their own citizens because of their inconvenient political views.
