I don't get this WW3 talk that seems to only be here on Lemmy. Like, does anyone actually expect any countries with significant global influence to line up behind Hamas?
The closest I can think of is Iran, and they're a regional power at best, and they prefer to work behind the scenes.
No, this will be a nasty little "tempest in a teacup" as always, with lots of onlookers wagging fingers but doing nothing. This is what all neighbouring nations are already doing - in fact they love the fact that Israel's disproportionate response is damaging their reputation. They're more than happy to stand by and watch, as they're the ones who set Gaza up as a punching bag in the first place.
Ukraine is far more likely to evolve into a global conflict, especially with Ukraine's position weakening and Poland chomping at the bit to jump in.
