What I’m rebutting—or rather making a poor attempt to rebut—is your hinting that the international double standard doesn’t exist, or at the very least is understandable. The interviewee in the al-Jazeera interview makes a much better argument for the existence, the importance of recognizing, and the inexcusableness of this international double standard, better than I ever could.
A short way to sum this up is: regardless of the distaste many in the west (myself included) have for the means by which Israel is pursuing it's goal, the west is unanimous in support of that actual goal: no western state believes Hamas should be left to govern Gaza, even as many probably do quietly hope to haul Netanyahu to the Hague (if the Israelis don't imprison him first).
Meanwhile: every western state actively, viscerally opposes Russia's goal.
Everything you wrote following the word "should" was abusive. Please don't write things like that; I've done nothing to merit incivility from you.
