The United States and Germany are the main opponents of Ukraine's invitation to NATO, although Eastern European countries and the United Kingdom insist on it. This was reported by Foreign Policy, citing sources.

Other Western representatives of NATO are also against it. They believe that Ukraine should not be admitted to NATO while the war is ongoing, so as not to provoke a conflict between the Alliance and Russia over the occupied Ukrainian territories. However, they generally support the accession in the long term.

It is believed that France is ready to send Ukraine an official invitation to become a NATO ally. Poland, the Czech Republic, and the Baltic states believe that only Ukraine's membership in NATO will convince Russia to slow down the invasion and end the war. Other supporters of joining believe that it will be cheaper than constant arms supplies.

But the United States has asked its allies not to force the issue at the summer NATO summit in Washington, to prevent Russia from talking about a split in the Alliance.

The publication writes that even if Ukraine receives an invitation, it "could take years" for approval by all NATO countries.
