Folks are so clouded by hostility to Trump that they cannot see that progress is actually being made towards some kind of resolution. Both sides have a ton of issues that they have not presented to each other in three years. The meetings and contacts so far are not useless as some appear to believe. Like Vietnam, or Korea, or even Afghanistan, stuff like this takes months. One thing is certain is nothing is gained by not bringing the parties to the table.
Rather, those who are clueless about the past are as naive and gullible as were previous generations about what real progress is - and doomed to repeat it. If they weren't historically untutored, they would know that diplomacy is merely the continuation of a war by additional means.
Like Vietnam or Korea, baring a major defeat of one side, negotiation does not take merely "months", it takes YEARS (4.8 years for Vietnam). And as with Vietnam, when one side is increasingly desperate for negotiations (LBJ, Robert Kennedy), and showing weakness by constantly halting or forgoing more aggressive action (e.g. Johnson's bombing pauses) to encourage peace, the other side is then milking it for advantage, and playing for time to deliver decisive blows that will determine the outcome of negotiations when time is right.
Much like North Vietnam, Putin has adopted this talk-fight strategy, making maximalist demands for more territory while waiting for the war to erode and outlast US resolve. Like NV, he is maximizing his leverage, exploiting US political divisions and targeting Trump's own weak resolve to gain or force Ukraine concessions.
So, most of these Vietnam war negotiations were merely for appearance, and to keep the bombing halt concession going. It ONLY made progress in 1972 when NV failed in its Easter Offensive and Nixon, to NV's surprise, restarted the bombing with B52 strikes devastating NV targets. The result was a US "face saving" agreement for US withdrawal and false security promises to South Vietnam should NV restart its aggression - which of course, it did.
All in all, it took 4 years and 8 months of negotiations, most of them a waste of time and provided the NVA and NV immunity from airstrikes above the 20th parallel.
So no, negotiations are not making progress. Progress will only be made when either Ukraine suffers a major loss and effectively concedes, or when Putin decides the pain is too great and there no more is to be gained.
So far Putin does not think there is no more to be gained, or that the pain is too great.
