“You have a fertile imagination.”
No, the regime does. I hope they allow the father to leave, though he said that he will not return home without his daughter.
They will use the father to their own advantage, whatever and however they see fit. If they determine that detaining him suits their needs, they will.
So to say that one be can “sure” that the regime will let him go is ridiculous.
I am sure. No need to speculate. We will see what happens and you will see whether I am right or wrong. I am sure I am right and you are wrong.
