Ask yourself if Germany and Vietnam go to war, would you fight for Germany against Vietnam? If you refuse to fight, you don't deserve to hold german passort.
You escape the socialist paradise of Vietnam speak volume on how you feel about its living condition. Now, I see you cheer for the bo doi vc who are the root of Vietnam's poverty and misery. Had those bo doi had any thought about their people; they would have removed the "Party" a long time ago. It is the bo doi who keeps the party in power; hence; they deserve to be spit on.
