Its just my opinion, but it's a hard no from me. Even if the US declines nominally on certain fronts, it is not necessarily declining relative to its peers. So it's it's influence is not really declining noticeably enough to signal qualitative change.
Yes there are plenty of things to be optimistic about, such as dedollarization and seeming to fail in Ukraine, but this will not be a fast enough process to blindside it. The US has time to adapt and disrupt the coalitions that are necessary to push forward and there is still time for mistakes on the part of coalition builders, or antagonistic contradictions developing among them.
Basically, even as the US becomes more and more vulnerable, everyone else is still vulnerable as well.
Also, the US has other weapons such as it's propaganda machine and imo it's never been more dangerous than it is right now. It doesn't need to be persuasive either, only disruptive.
Most importantly, very few people in the US seem to actually want it to fall. This important because even if the US seriously stumbles, it is more likley that Americans generally will seek to recover it's footing instead delivering the killing blow and moving forward in a decolonial and anti-imperialist direction.
At the same time, however, I feel like most of the security the US enjoys is something that could collapes relatively quickly. I just think I would be too optimistic to believe this must happen anytime soon instead of under other circumstances such as a highly developed alternative international coalition and an organized front at home. The BRICS still have work to do imo, but indeed the ball is rolling, just gotta pick up the pace.
