America is a bit overstretched at the moment. As far as I can tell, we spent about 50 years in the cold war talking up liberty and democracy, but that was essentially all kind of a BS cultural-supremacy soft-power fig leaf until the cold war ended. Then we had about 20 years of politicians who thought the soft power stuff was all you needed. About a decade of unwinding that position, and the new paradigm is to get back to creating a global order and dispatching regimes that disrupt our commerce. The security concerns haven't changed, but the way of dealing with them has.
The only trouble is, we are no longer the superpower that we were in 1950 or even 1980. What I think will be interesting from this realignment is how our alliances will probably shift toward countries which are strategically aligned with us even if they're much less ethically or ideologically aligned with our stated beliefs.
South Korea and the Philippines are both "capable allies" in the sense that Israel and the UAE are, and in the sense that much of Europe is not. I'm confused as to why Filipinos are protesting against taking out the Iranian regime; it's a direct blow to Chinese expansionism, as well as the jihadist groups in the south. But America's taking out the weakest links in the Russian-Chinese-Iranian-Venezuelan axis. A short-term rotation away from East Asia doesn't necessarily mean it's a bad strategic move.
