This is probably incredibly naïve but wouldn't it help us get a "friendly" airfield if we could say something like "you can allow us to use your airfield or we will move in our ships in N hours anyway". Am I missing something here?
One announced U.S. strategy in the Pacific is to spread forces widely rather than concentrate them, and to utilize bases of friendly nations (who don't need U.S. coercion these days with the Chinese government coercing them right into America's arms). The U.S. recently made such agreements with Australia, The Philippines, Vietnam, and Singapore, and of course has long-standing bases in Japan and South Korea. Indonesia is almost the only major nation left in the region who isn't on board.
When things get serious, thoughts like "I would never do such a thing!" are quickly cast aside.
I definitely feel that played a part in allowing Germany in WW2
