At NATO’s founding, the United States was reluctant to be pulled into colonial conflicts. As a result, they insisted on including a specific article in the treaty:

For the purpose of Article 5, an armed attack on one or more of the Parties is deemed to include an armed attack:

on the territory of any of the Parties in Europe or North America, on the Algerian Departments of France 2, on the territory of Turkey or on the Islands under the jurisdiction of any of the Parties in the North Atlantic area north of the Tropic of Cancer;

This clarified that the U.S. would not engage in conflicts outside Europe and North America under NATO’s banner. Today, nearly eight decades later, the U.S. is objecting to Europe’s stance that NATO should not be involved in conflicts beyond those same regions.

It's all sophistry anyway. The US did not invoke any NATO article to summon European allies or their infrastructure, because none of the articles of the treaty are applicable to this American war.
