One difference you forgot. Texas situation was one city or portion of the state...Puerto Rico is the whole state/island. There is no neighboring cities to come and help. They have no water, electricity, food, gas etc. All the conveniences we have they have nothing. How do you deliver goods without gas? How do you clear out trees and poles from you roads without equipment? One could do this by hand but it will probably take more than 10 days for some progress. You think?
