The part about the moral case against Russia isn't an opinion. Here's the Financial Times a year ago:

“We have definitely lost the battle in the Global South,” said one senior G7 diplomat. “All the work we have done with the Global South [over Ukraine] has been lost . . . Forget about rules, forget about world order. They won’t ever listen to us again.”

“What we said about Ukraine has to apply to Gaza. Otherwise we lose all our credibility,” the senior G7 diplomat added. “The Brazilians, the South Africans, the Indonesians: why should they ever believe what we say about human rights?”

Just four weeks before the Hamas assault on Israel, leaders from the US, EU and western allies attended the G20 summit in New Delhi and asked developing nations to condemn Russia’s attacks on Ukrainian civilians in order to uphold respect for the UN charter and international law. Many of those officials told the Financial Times they have had the same argument read back at them in demands for condemnation of Israel’s retaliatory assault on Gaza, and of its decision to restrict water, electricity and gas supplies there.
