Yes you are correct, there is a lot of Swamp and as I've mentioned, Russian are making best advancements around this area, but as I've said with situation around Kharkiv, it might help with disrupting at least some of the Russian opperation. And it has already happened after Ukraine seized back Staryi Saltiv. Also there are already emerging reports, that killing off general Semionov at Izyum might have sown some chaos into command line of the Russian forces at the area of Izyum. And almost all of the gains in Kharkiv area have taken place after the alleged general's demise as well.
Yesterday report from ISW: Ukrainian forces continued to threaten Russian ground lines of communication to Izyum along the E40 highway, destroying a Russian supply convoy in Vesele on May 3.
Answer to both of you, there are rumours about Israel willing to offer Ukraine their Iron Dome, especially now after Lavrov went full anti-semitic. I have absolutely no clue how that might be plausible, so I am just posting it here as one of the theoretical options here.
Two general's deaths is being disputed now, as they allegedly shown themselves on Russian TV after the alleged hit. But knowing Russian propaganda, this might be a prerecorded footage to deny Ukrainian claims. And of course this could be also Ukrainian propaganda to boost little bit their soldier's morale... And There are also two unnamed generals, who allegedly died during bombing of command outpost in Kherson area, with pretty high number of lower ranking officers dead as well. This attack has not yet been verified by independent parties though. So the number of dead generals is currently between 8-12.
Putin was not in the previous 20 years hidden without contact to other people. Since the start of COVID, he spent almost entire 2 and half years completely isolated with very few people able to contact him. Even the strongest people might get mental health problems when isolated for such a prolonged time.
Also speaking about the Russian negotiations, well, their tactics since Syria is to pretend, that they want to negotiate with you, just to divert your attention to somewhere else, so they can stab you in the back at the first possible moment. But it looks like, that the West have learned hard lesson from Syria. Any negotiating efforts from Russia could not be taken seriously. Especially with all the gas and ores around Crimea and Donbas... Negotiations is just another means of waging their war.
In Syria Russia offered deescalation in one of four areas of control in Syria, for the start of "negotiations" and while west was busy and happy about that one area, Russia snatched three others and obliterated them. And in the meanwhile, they were having "negotiations" with UN as well, which ended up with UN not having any significant reaction to Russian onslaught of civilians and civil infrastructure.
The excerpt from one of many articles on how Russia is misusing "negotiations" to deceive the other side:
"Negotiate As If There Were No War and Bomb As If There Were No Negotiations
In 2015 Russia decided to take advantage of the vacuum left by Western actors and engaged in Syria on three levels simultaneously: militarily, diplomatically and politically. One of the common features of the wars in Syria and Ukraine is the Russian strategy of negotiating as if there were no war and bombing as if there were no negotiations. On all three levels, Russians have outdone their Western counterparts. Highly capable Russian diplomats have upheld political dialogue and, at the same time, kept the military option open. Both reinforced each other. Sitting at the table opens options in case they are needed. During the talks a peaceful narrative could be fed to the media, reducing international outrage and allowing a regrouping of forces."

Note, that the same strategy was deployed during Phase 1 of Russian invasion of Ukraine, but thankfully, they failed this time to spark the international outrage against bad west trying to sabotage the peace talks...
