Improvised empirical test:

Countries capable of projecting military force like that: 3-4 (4 if we count Russian paratroopers)

Countries "cut off" during the last decades: 0,
unless we count aggressors who were under a UN blockade


Another approach:
Japan:
* 2nd most powerful fleet in 1941
* biggest or 2nd biggest marine force in 1941
* 4th greatest air force in 1941
* still cut off from crude oil supplies (would not have happened with a more peaceful foreign policy)
