The US is the third most populous country in the world, and it's GDP is comparable to the entire EU, and almost twice China. And it only spends ~2% of that on defense. Do you understand the relative scales here? Military spending per capita per area is quite comparable to other nation's spending. With the amount of shipping and money that flows through the US, it would be absurd to leave it inadequately defended.
>it's considered above-sacred to allow this military machine to do literally anything it wishes to do
It doesn't do anything it wishes to do, it does what politicians wish it to do, and what it does is "protect US interests", which is exactly the same thing every other military force on the planet does for its host nation.
>is now a good time to mention the Bikini atoll?
No, you're probably 60 years too late to bring that up.
