Well, surely you remember the Mariel Boatlift, don't you?
Castro agreed with Vattel that citizens should only be held captive so long as they remained useful to the State. Castro, like Vattel, was happy to let some citizens escape if he didn't want or need them anymore.
Like Vattel, Castro just believes that the State has first claim on the labor of its citizens.
Don't you agree with Vattel about that feature of citizenship?
Don't you believe in natural law?
Don't you agree with Vattel about that feature of citizenship? Don't you believe in natural law? Don't you believe in READING COMPREHENSION?
Saying we have to take the FIRST part of something without being able to consider the LAST part of something is like saying a court has to hear a case but can make no decisions.

Get your Castro issue checked. Seriously.
