Would you mind listing all the naval security commitments - from the Bretton Woods era - that the US has withdrawn from (eg over the past decade or so, anything relevant to "continues to")?

I'm not aware of any meaningful reduction in US naval security commitments. If anything the US is as busy as ever with its global naval security efforts. It's hyper busy everywhere: from Latin America, to Australia, to Europe, to the Middle East, to Asia.

The notion that the US has stepped back at all is entirely unsupported by the actual facts. It's just a weak myth being posted endlessly since Trump began spouting isolationism in 2015-2016. Meanwhile, in actuality, the US just spent another hundred billion dollars on a foreign war in two years.

40 years ago the US Navy was equipped and staffed to patrol the global oceans. Now, the US has a relatively few massively powerful forces of naval power projection but is woefully understaffed and under-equipped to maintain the global order against multiplying chaos. This is unlikely to change at all let alone be fast enough to influence outcomes. Growing sentiment after decades of the war on terror is for the US to be hesitant to intervene internationally, and while that isn’t current policy it’s predictive of future policy. It’s not at all clear that it would be popular in the USA to, for instance, go to Moldova’s defense.

> the US just spent another hundred billion dollars on a foreign war in two years.

The vast majority of this was accountancy fictions about the value of stockpiled obsolete materiel we couldn’t sell but had to pay to maintain or pay to scrap. We have demonstrably not gone all in on supporting Ukraine and Congress is currently strangling any attempt to do so. This is another sign of the US inevitably devolving into an unreliable defense partner.
