Completely agree. The modern equivalent of the Berlin Wall has already gone up (i.e. sanctions and divestment) and will stay up for at least one generation.
However, Americans underestimate how much our own influence is shrinking. I traveled to many countries in the last two years, and found that most people associate America with its most extreme ideologies (QAnon, gender theory, Trump policies, etc). The Russian bloc of the upcoming Cold War v2 will likely coalesce around the notion that America/Europe has no right to dictate global policy.
