Only in the same way that saying he will end a hostage negotiation means he hates hostages. The context of how he will do it matters. Shooting the hostage does technically end the negotiation, and that's the equivalent to what he is suggesting. He would just have Ukraine surrender or at least cede territory which would only appease Russia for so long. We know this from history. Without due consequence, this is just rewarding Russia for their bad behavior. But trump is incapable of understanding behavioral consequences because he's never not been rewarded for being a selfish asshole.
