"Falsehood flies, and truth comes limping after it, so that when men come to be undeceived, it is too late; the jest is over, and the tale hath had its effect: [...] like a physician, who hath found out an infallible medicine, after the patient is dead." —Jonathan Swift
The difference: Israel is in Syria for imperialist aggression. Ukraine is in Ukraine to protect their homeland from imperialist aggresssion. Combine that with Israel's pathological need to cover up and deny their extensive, seemingly neverending war crimes in Gaza... Yeah, I don't have any faith until Israel can prove this was opsec rather than covering up. Israel has destroyed their chance for benefit of the doubt.
Even if it is opsec, they have no right being there, so fuck 'em. I hope their opsec isn't maintained and their soldiers do die in much the same way I'd hope for a Russian base in Donetsk.
