International diplomacy requires two things

1. An agenda

2. A politician with the will, creativity, and charisma to carry it forward

Biden has neither. But his missing elements in the second part don’t matter because there is no first part. Biden didn’t come to Europe with an agenda. His foreign policy is being run by the same old Obama people. And they never especially cared about Europe beyond using it to mobilize whatever third world agenda was animating them at the time. Biden’s people haven’t quite gotten all that far making the visit pointless.

Biden is in no shape to take on Putin. But he wasn’t even in any shape to take on Macron. Boris Johnson had to prop him up half the time.

Never mind trying to mobilize some sort of stance against China, a proposal Biden doesn’t believe in, but that some of his donors expect him to pay lip service to.

Biden’s trip to Europe is reminiscent of  Khrushchev’s trip to America. Despite American expectations, the trip had little diplomatic significance, it was intended for domestic consumption. Khrushchev needed to convince Russians, especially his rivals, that he was a player on the international stage. Biden’s trip is meant to sell him to Americans as a world leader even if no one in Europe is buying it. 

The European trip isn’t meant for Euros, but for Americans.
