If your country is conquered, you are ordered at gunpoint to open the safe full of gold. The same thing would happen with bitcoins - you're ordered at gunpoint to send them to the winning party. To be honest, if your country is conquered, the last thing the winning party wants is a couple of bits and bytes on a hard drive. What's far more valuable is the natural resources, workforce, factories, etc.
