> The world bought only 20% as many treasury bonds in the past year as in the year before that. This is what a slow decoupling from the US reserve currency looks like.

That's not what a decoupling looks like. Investors are probably just not buying because they know rates are going to go up. The Federal Reserve already strongly signaled another rate hike by end of year. Why would you buy something today that you can wait and buy for a better price later?

Second, if you want to make an argument about interest rates or the debt, you first have to make that argument and resolve it for the UK, Italy, France, and others.

Third, the USD is just the dominant reserve currency. It's not the only one. A reserve currency is just one that banks hold in reserve. The reason the US is involved in the Middle East is to protect the Petro-dollar which generally "requires" oil purchases to be settled in dollars. The trade off is we keep Iran in check from destroying the gulf countries.

> The US is the most oil-dependent country (although all western countries are quite dependent on it) and it cut off its own supply of oil.

This doesn't make any sense. The US is also the largest oil and gas producing country in the world. Even for the Strait of Hormuz and Red Sea you can read for yourself that the US has been able to break through and Saudi Arabia has quickly repaired the east-west pipeline and 3.5+ million barrels are flowing through there now (IIRC 60% or so of pre-attack volume). Either way, most of those flows go to Europe and Asia, not the US. So while the US is oil dependent (all countries are) I don't think your assertion is entirely accurate.

> It's been unable to manufacture anything effectively for a while now as all the money gets siphoned off corruptly (identical to Russia in the Ukraine war), not even the weapons used in Israel.

That doesn't make any sense either. We manufacture all kinds of things, including incredibly advanced equipment. We make airplanes, we make semiconductors, pharmaceutical goods.

> What else is there to being an empire? Its nuclear aircraft carriers - with no aircraft since they run on oil?

If we don't have oil neither does anyone else. Except that we do have oil so our nuclear powered aircraft carriers would just use our own oil for the jets.
