Can't blame their home countries for that. When that incompetent, worst ever (at that point) president carter accepted the challenge to accept Cubans, castro emptied Cuba's prisons and insane asylums.
Gotta respect the opportunistic logic. The fault lies with the naïveté of the boobs in charge in the country doing the inviting.
You are on track, this all started back when “Carter the Useless” deposed the Shah of Iran.
No, I understand why they do it. It galls me when the governments that take them in think we cant see it, dont know it when we do, and think they can righteously shame us when we call it out.
