I would not blame the band
Historically bands go to give the people something they’ve never seen
Like Metallica in Soviet Union in the mid 80s
Cuba will fall now at some point
These guys are going to die off
And plenty ex Cubans nearby just aching to exploit it
Might not be peaceful even now
No reason we couldn't have made that happen earlier rather then later.
Think of the people who would have lived had we done that.
