My personal opinion is that, it's because with the previous political and cultural trends, West had (maybe still has) actually quite high chances of collapsing and falling in the long term due to its own indecisiveness, lots of words mixed a lack of actions against coordinated and targeted efforts of Russia, Iran, Venezuela, Belarus, Cuba, China, Syria and North Korea.
I remember national state TV in Russia talking about "we are ready to nuke United States if needed" in 2014 [1].
So, domestically, government made sure people believe that the West is the mortal enemy and we were are already at some kind of cold war since Crimea annexation, it's just West didn't notice, seems like.
Then, there were also artifical immigration crisis at EU borders created by Russia and Belarus.
And many other various hybrid and asymmetrical attacks.

So, USA recognized the danger and started dismantling the problem piece by piece, to ensure a long term peace and safety of its people. Could it be better organized and coordinated with allies? Probably, yes, but the meaning stays.
