Yeah, but Russia invaded Ukraine. So what should be done now.

What about putting sanction on china for providing russia weapons or on emirates and turkey for allowing russian to just chill there and bypass restrictions?

If left to their own devices, Ukraine would be annexed to Russia and surrounding countries would be next.

Where do you got this from? Is Israel planning to invade the whole middle east after they invaded gaza?

the quality of life of the Ukrainians would drastically degrade.

Would it actually? Ukraine turned into an authoritatian regime under martial law where no man between 18 and 60 can leave the country. There's probably many brave ukranians fighting for freedom but it's the ukranian government getting money and weapons.

The casualties are already high and the country is getting destroyed, it's just not happening in your garden
