Sanctions are always meant as collective punishment, it’s a siege warfare tactic. The goal is to torture innocent Cuban people for not overthrowing their government, starve them until they have no choice but to destroy the revolution. America has even directly admitted it:

to weaken the economic life of Cuba . . . [to deny] money and supplies to Cuba, to decrease monetary and real wages, to bring about hunger, desperation and overthrow of government.”

This is the same policy as in Gaza, to starve the people until they turn their backs on the enemy.
