I don't think the US will be overtaken on the outside, but there are issues inside. We're kinda tearing each other apart. And respect for the rule of law has been under attack, including by respected institutions. If that goes, we're in trouble.
Six years ago, I took a group of 20-year-olds on a long hike. They commented that "times sure were bad for our country." I smiled and told them that things were fine, compared to the harder times of Jim Crow, Lynch Law, Great Depression, Civil Unrest in the '60s, the Vietnam Era, and the Stagflation/Scandal-plagued '70s. By comparison, I assured them, 2012 was just fine. Since then, my opinion has changed considerably. There is a measurable threat that we are tearing ourselves apart.
We were tearing each other apart in the 60s, too. And the 30s. And so on.
That's not to say that there aren't serious problems, it's just that I don't see what's so supposedly fundamentally different about them this time around.
