20th century means that we’re talking at least 2.5 decades ago. That’s a long time. And for the most part, US foreign policy regarded much of those actions as folly even if they will never say that publicly.
You’re absolutely right with your assessment but beyond that this is also a rolling back of the clock to thinking from decades ago.
Yes, but that was because there was a golden age when the west dominated the world without facing serious rivals. There was less need for interventions and the west was deluded (by wishful thinking) into regarding this as a permanent shift.
Even in the last 25 years the US has fought in Afghanistan, bombed Libya, ISIL held territory, Syria, blockaded Yemen and probably more.
The world today is going back to a cold war like rivalry between the US and China so we can expect both sides to use much the same tactics.
When the Soviets were literally standing 60km from Vienna with tank brigades a lot of bullshit was easier to swallow.
Right now it seems like totally unnecessary destabilization. Don’t even get me started on proposing to seizing NATO territory by force in Greenland.
