@blueshoes true. But in the wider view it means that China, who is really against the West, is not supplying weopons and that is a really big thing. I thought tbh they might quietly do so on the sly. Other countries have also taken the view that they aren't going to supply Russia
With every respect and then some to the defenders in the Steelworks, the chances of them surviving in the first place were very low. If they die, they have died with purpose, though that will not soften the grief of their families much. But in the end the Kremlin claiming Mariupol is not the greatest problem.
We need to keep the greater picture in mind too though. The greatest problem is twofold: stopping Putin's expansion into Eastern European countries and keeping Ukraine free.
Stopping Russia now is about making sure that Poland, Estonia, Lithuania, Romania, Bulgaria do not end up back in the Russian empire unless they themselves choose to go there (we -have- to respect countries' free choice, or democracy means nothing. We have to respect Hungary's position much as I despise it, and think that their position should have consequences: removal from the EU and from NATO. But supporting Russia has to be their choice, if they want to go that way).
Mariupol is a destroyed city, a hellscape of grief and despair.
We need to work now towards defeating Russia militarily and finding a solution out of their defeat that allows them to withdraw while still claiming victory, to save face. We need to think of how to save the cities of Kharkiv and Kherson and Odesa from Mariupol's fate, which might happen if the Kremlin has to face the fact they have lost. I'm afraid that many of the towns and villages in Donetsk and Luhansk are probably lost.
I have no solution as to how to ensure that the populations of Kherson, Kharkiv and Odesa are not kept safe and the buildings and infrastructure are not destroyed. The only way I can think is to defeat the Kremlin roundly and make some sort of realistic threat that if those cities are destroyed then -some- vengeance will take place on Russia, the Kremlin and Putin that will make even the hawks back down. What that would be, I don't know.
But I think we need to think beyond only Mariupol now.
