If the US wants to abdicate their position as a global hegemon of every waterway and trade route this seems like a good way to do it. The US is much less dependent on the Strait of Hormuz than its competitors.

Ten years down the line it may be the case that India will sail up and enforce toll-free waterways instead. That will never happen as long as the US puts up the resources for it. The American taxpayer will be better off if the burden of global free trade is borne more equitably.

It's not like the US did massive world wide power projection (capabilities) out of altruism. It's a necessity to project their political and economic demands.

If the US citizen think being a super power is to expensive, that's fine for the world. No empire lasts forever. The US can become an important regional power, having its destiny more influenced by the upcoming super powers that fill the vacuum.
