The Viking Age shouldn't surprise any of us I suppose if they violate the you know ironclad supposedly ironclad 1980s rule uh that you don't negotiate with terrorists because they do all the time. One of the things that they do in order to get the protections that that they seek is give up land now before we get carried away. These sorts of arrangements that the Romans made with barbarians that ended up destroying the western Roman Empire yeah but if it bought you generations of safety before it poisoned the Roman Empire was that still maybe the right decision for the people at the time to make?
