If there's a political motive in not choosing an American pope until now it's that for most of American history it wouldn't have granted them any influence over American politics. If there's a personal motive it's that until recently they felt insulted that America went for almost 200 years before finally electing a Catholic president.
Are you suggesting that the decline has only been apparent since Trump's re-election? For some (myself included), America has been in obvious political decline for some time - highlighted and spurred along by some significant events (Trump's first election and the nature of US involvement in Gaza to name a couple).
The reason I said "four months" is because America's media establishment has been pushing this narrative that the tariffs and the argument with zelensky have somehow ended american hegemony overnight; I personally believe it's impossible for these events to cause a noticeable decline on such a short basis because there's far more to america than merely not taxing imports and giving limitless amounts of free stuff to ukraine with no strings attached, but I have developed a pavlovian response to the phrase "America's in decline" because it really is all about Donald Trump with these people.
I would personally put the origin of "America's Decline" at 9/11 because that was the beginning of America's self-doubt about what their place in the world is and what it should be. Everything since then has been the five stages of grief on a nationwide scale. Currently we're somewhere between Depression (stage 4) and Acceptance (stage 5) which is why we gave up on Afghanistan, and also why so many people are opposed to funding Ukraine; there's a legitimate fear that arming the Ukrainians will in some way come back to bite us in the ass 20 years later just like arming the mujahideen did.
