We've been here before, and done a much better job of it. What job? Supplying a cut off population with the wherewithal for existence. Read up on the Berlin Airlift. It began in less time, post loss of access, than Donald J. Quisling has done with Puerto Rico and the USVI. It was, of course, run by the US military. Stodgy establishment.
The day after the 18 June 1948 announcement of the new Deutsche Mark, Soviet guards halted all passenger trains and traffic on the autobahn to Berlin, delayed Western and German freight shipments and required that all water transport secure special Soviet permission.
On 25 June 1948 Clay gave the order to launch Operation Vittles. The next day 32 C-47s lifted off for Berlin hauling 80 tons of cargo, including milk, flour, and medicine. The first British aircraft flew on 28 June. At that time, the airlift was expected to last three weeks.
Granted, the Berlin crisis had been on-going for some time, but Donald J. Quisling's dismissal of Puerto Rico is of a piece with W's disdain for New Orleans; now essentially white-ified.
