From a ruSSian point of view it’s probably the most sensible tactic and one they can all live with because they have no fucking decency. They make the steelworks “out of scope” and declare victory in Mariupol.
Not allowing the civilians and wounded to be evacuated is grotesque but we’ve come to expect nothing less, noble or decent from these horrid cunts.
It's the most sensible point of view from everyone's perpsective if you spend 5 seconds thinking about it instead of going off like this is a video game and the only goal is to kill Russians.
A frontal assault would kill loads of Ukrainian civilians and military. Not just any military, but some of Ukraine's most experienced and battle hardened.
The siege is going to mean the Ukrainians decide the timetable of defeat which keeps the possibility of a rescue or resupply open until the last possible moment, and it means many will surrender and eventually get recycled back to Ukraine just like thousands of POW already have.
