There's no chance NATO'll grant Ukraine membership. It is right next to Russia, and NATO is scared to upset Putin.
There's a good reason that Zelenskyy states often & publicly that they'll take back Crimea. It is because, imho, NATO would be happy for Putin to have Crimea as a face-saver. But the Ukrainians have lost too much and know that kicking Russia out of every inch of Ukraine is the only guarantee that they'll be safe from future special operations.
NATO likes a weakened Russia but still wants to appease Putin. May they're afraid of what'll happen if he gets deposed. Or maybe he has kompromat on the leaders.
