Ukraine has to win the war with Russia before becoming a NATO member, U.S. National Security Council spokesperson John Kirby said at a briefing on June 17.

His statement came a few days after Kyiv and Washington signed a 10-year bilateral security deal at the Group of Seven (G7) summit in Italy, recognized as a "bridge to Ukraine's eventual membership in NATO."

"(U.S.) President (Joe Biden) believes firmly that NATO is in Ukraine's future at some point," Kirby said.

In his recent remarks, Biden said that peace in Ukraine means a guarantee that Russia will never occupy the country again, "and it doesn't mean NATO (membership)."
