Russian President Vladimir Putin on Saturday hinted that the Ukraine war could soon end. Speaking to reporters after marking Russia’s Victory Day parade, Putin said: “I think that the matter is coming to an end.” The comment was made in response to a question about whether Western help to Ukraine went too far. The Russian leader said: “They started ratcheting up the confrontation with Russia, which continues to this day. I think it is heading to an end, but it’s still a serious matter.”
Putin’s remarks come as Kyiv and Moscow observe a three-day ceasefire in Russia’s war in Ukraine this weekend. The truce was announced on Friday by US President Donald Trump after negotiations brokered by Washington. European Council President Antonio Costa on Thursday said the European Union was prepared to hold separate talks with Russia and Ukraine “when the right moment comes."



Both countries are functionally out of gas.
From my understanding, Russia is running out of gas and their economy suffering significantly.
Ukraine is getting stronger and better defended. If they run out of money, they may be in some trouble, but that doesn’t seem to be looking likely anytime soon (large influx of EU money coming soon).
Ukraine can trade small amounts of land to allow Russia to grind its self down (Pyrrhic victory after Pyrrhic victory). Eventually Russia won’t be able to sustain their momentum and can be pushed back then (already seeing some evidence of this beginning).
