The communities in NY and other Northern states are already getting together to help. Problem is that flights out to PR and the rest have been cancelled and will remain so until further notice. It si dangerous to send help under those conditions so people will have to fend by themselves a long time.
Since RD is an ally, I hope Taiwan can help rebuild. Though depending on the effects of the hurricane, China might use that to muscle in. St. Kitts and Nevis, another friendly, is also in harm’s way.
