They need our arms, intelligence and military input. They’ve managed to counter the Russian glide bombs, which were devastating them for months and allowed Russia to take a substantial amount of land. The lines are virtually frozen with Russia losing huge amounts of troops and materiel for every meter they now take.
IMO the solution now entails Trump being tough, actually. The solution is to admit Ukraine to NATO on a date certain in the near future at which point the lines become permanent. Trump needs to forcefully tell Putin that at that point if they attempt to cross those lines, NATO article 5 is invoked in the United States and all the other NATO allies will enter the war. Putin could not win that war. You know it. He knows it. Everybody knows it. The only threat he has are nuclear warheads, which is a zero sum game.
Putin would be forced to quit.
