Both can be true.
If everything is Cuba’s fault, then US can lift sanctions and they’ll continue to be failing. But they won’t do that because Cuba, while awful for speech rights, would be pretty good in most other aspects without the sanctions, and a successful socialist country isn’t allowed to exist.
Serious question: while air drops are likely dangerous and ineffective, are they better then nothing? Bringing aid in by land/truck is impossible right now, so the comparison shouldn’t be to that; it should be compared to getting nothing at all.
