He isn't stalled. From what i can tell. He's giving them plenty of time to leave before the real fighting begins. That is what would be called an act of kindness or nobleness in war. They didn't run out of gas or food 236 miles away from the Russian border and there isn't some raging fight going on either.

Or NPR

Or NPC.org for that matter

he doesn't need to double down. he has the land he was assigned already.
