Blaming any of this on anything but a hurricane is absurd. Ive been through hurricanes and the aftermaths 2 times without power for more than a week. Just getting it back on is a giant undertaking in the US where we have the resources to stage outside of the storms path and then bring in quickly. Now think how hard that would be on a damn Island. You simply can not prepare for something like this adequately and the response is going to be fragmented due to the logistics and amount of damage. Compound this with the fact that we are still in the midst of dealing 2 disasters on our mainland..and you have a recipe for major problems.
IMHO the US is doing all it could be expected to do under the circumstances.

Can we do better?...Probably. After this is cleaned up and back to some level of normalcy we should sit down and rework disaster plans for the PR based upon this storm. Now is not the time to point fingers. Now is the time to get as much help as possible to them as quickly and safely as we can. We can discuss what worked..and what did not...after the crisis is over.
