Are we worried the Australians are going to pick up the toll road and plop it down outside Sydney ?
No, but in a war time scenario, they could certainly forbid the passage of US military vehicles on the road, if they wanted to
Then those properties become immediately seized and nationalized under the Enemy Act
So we get to keep the road, their equipment, and their money? Cool. How soon before the Aussies and the Spaniards declare war?
