I think you misunderstand. I'm not American. "Time's up" means that I'm done waiting and hoping that America will get its shit together, it's time to treat America as an adversary rather than an ally and move on. The pattern has been clear for a long time, this isn't new. It's just reached a point where it can no longer be papered over and ignored.
The "big thing" you're hoping for - a sudden dramatic move to national sanity by the Americans - isn't going to happen without generational change and a fundamental shift in world power dynamics happening first.
