NATO came into being to deal with the USSR, which was the preeminent threat to all NATO members. The US wasn't expected just to come save Europe; European states had real military power and the will to bring it to bear against the US's main adversary. In a conflict with the USSR, the US could rely on Europe to fight with them. Very valuable.
Today, US policymakers see China as the main adversary. But European states have no real military power--certainly none that can be projected in the Pacific theater--and wouldn't have the will to deploy it even if they did. Europeans now expect America to fight Russia for them, not with them. So now NATO is basically all risk and cost for the US with no benefit against their main adversary.
I think it's a shortsighted view of American national security imperatives: American security relies as it ever did on security in both Western Europe and Eastern Asia. Abandoning one theater to focus on the other just leaves a giant blind spot.
However, this has led Europe to take its own security more seriously and stop relying on America to fight the Russians for them, something multiple POTUSes have tried more diplomatically to achieve--and failed--for decades.
