Virtually impossible in the current dynamics of the region, and I don’t think this has ever happened in history.

People have been saying the same thing about China and Russia since they got in a pissing contest in the '50s. Or if some fraction of Africa ever decides to work collectively. There are lots of 'what if...' scenarios that will radically change geopolitics and do wake me up when one of them comes to pass...

Maybe? In concrete terms I'm not sure what that means.

Both countries are going to work to their individual interests like they do today.
