The U.S. administration has drawn up an internal ranking of NATO member states, grouping them according to their level of contribution to the alliance, Politico reports. The existence of the list was confirmed to the publication by three European diplomats as well as a Pentagon representative.

According to those familiar with the matter, the White House created what is described as a «good and bad» classification of NATO countries as it looks for ways to respond to allies who declined to back the U.S. in its confrontation with Iran. The remarks were conveyed indirectly in the report.

Sources indicate the document was prepared ahead of NATO Secretary General Mark Rutte’s visit to Washington. It categorizes member states based on their participation and overall input into the alliance’s activities. However, the report does not disclose which countries appear on the list or how they are ranked.

Earlier, U. S. President Donald Trump had publicly raised the possibility of withdrawing the country from NATO. The statement came after a number of allies chose not to support Washington’s actions against Iran. He viewed their stance as a serious blow to trust within the alliance.

French President Emmanuel Macron had criticized the U.S. operation, arguing that it went beyond the bounds of international law. UK Prime Minister Keir Starmer also distanced London from the situation, stressing that the conflict did not concern Britain.
