Do you really think that is how this is going to play out. The government telling San Diego to go pound sand and that will be the end of it? I’m in favor of that result and then they can build the airport in the desert for all I care.
More likely IMO is that politics will come into play and a number of options will be on the table including ones we have discussed and you have slammed. I know nothing about the process involved though and have no idea who or what would be able to pressure the military to accept a joint use airport at Miramar (most likely outcome IMO).
