Trump's envoy, Vitkov, stated that in the negotiations to end the war, Putin is inclined to make some concessions, including agreeing to the strong security guarantees proposed by Trump earlier, even though these guarantees are not under NATO's framework. Secretary of State Rubio, on the other hand, took a more cautious stance. He warned that both Russia and Ukraine need to make concessions to end the war, and a peace agreement is unlikely to be achieved in the short term.
