What Plans Does NATO Have in Case the US Leaves the Alliance?

According to Politico, NATO has no contingency plans for the United States withdrawing from the alliance, citing three diplomats from the military coalition. The report notes that the United States plays a significant role in NATO, and therefore, its allies cannot plan for the future without it.

One of the paper's sources stated that this situation "contradicts the very purpose of NATO." Moreover, another source mentioned that the diplomats interpret Washington's signals not as a precondition for the US's withdrawal from NATO, but rather as a powerful call to action for Europe.
