For my money, Biden, Austin, Sullivan and Blinken have been playing the Stradivarius in this crisis. They can't do more than they have without changing the dynamic for the worse.
Look at the alliance. Its strong. its got the free-riders stepping up in big ways and vocally. Germany spending $100B on defense with an SPD government!? unfreekingbelievable.
Trump shit on the alliance and created resentment. He shoved member leaders out of his way at conferences. He sent his children in to shake down those who sought influence. He allowed the dumbest forces in American politics to destroy the fabric of internal order in the country to the point where Putin thought January 6th was the true face of the country.
