Sometimes negotiations start with large broad ideas and concepts, that aren't always doable. Then the process gets whittled down to a deal. For example, in our Kansas City, Clark Hunt may be trying to angle to have someone else pay for an entirely new stadium, but he may have to settle for someone else paying for the majority if not all of the renovation of the current stadium. Again, depending on his ultimate goal. Either way, it's still a win-win for Clark Hunt.
In this case, a good deal would be broader access for the United States to Greenland's natural resources, shutting out not aligned entities from that goal, and for a more substantial military footing for that hop off point for the Arctic.
