It was the UN that created the state so it's a bit rich of them to chuck that accusation. And their condemnation of China has been very muted at times, the WHO even praising their handling of covid. Amnesty I have more respect for, but the apartheid accusation has not been generally accepted and has been heavily criticised. Israel, for all its faults, is a democracy. Arab citizens can vote in general elections, and Arab parties sit in parliament. There are Arab justices on the Supreme Court, and Arab doctors in the health service. All of this would have been unthinkable in apartheid South Africa. How the Israeli army behaves in the occupied territories of course is appalling. But they stopped counting the dead bodies in Iraq after the US and UK invasion. So glass houses and all that.
The role of Britain in shaping the borders and the conflicts of the Middle East is huge. I would imagine that Morrissey as someone of Irish descent, and another part of the world where partition didn't work out too well, as far as Israel is concerned just feels obliged to sing his songs and rise above all the grimness of history, and current events.
