Exactly, what are they going to do that’s new? Take more territory? They would have already if they could. Target civilians? They’re already doing that. Use banned weapons? They’re already using various chemical agents and white phosphorous, so nothing new there.
The only real escalation they have left is nuclear, and that would 100% result in countries retaliating with their own, ending us all. Besides, then they’re still just left with more irradiated land than they already have, there’s no benefit.
Are they trying to claim they’d be capable of maintaining a war with multiple fronts if other countries openly join in retaliation? Because if they had more military in reserve, they’d surely be sending it to Ukraine to end this “2 week conflict” as quickly as possible.
