He wants her to pay the price for his pain, without seeing that nobody ever paid the price for hers. It isn't that she cherishes her homeland more than her son. It's that she was betrayed and cheated, and he represents that betrayal.
I don't excuse her negligence of her duty to him. But I very much condemn his choice to disregard his father's sins against her. You can't expect a woman to be a good mother after blackmailing her into making a baby.
