Attacking targets that are only available because the “enemy” is following nuclear treaties is one of the more cowardly war moves I’ve seen. Leave it to Ukraine to have done it right before peace talks while asking for a ceasefire. I’m having a tough time sympathizing with them. They seem to be begging for Russia to respond with nuclear weapons.
That is false information:
a) Russia decided not to follow the treaty themselves. Your information is false (by more than a year).
https://www.armscontrol.org/act/2023-03/news/russia-suspends-new-startb) Each time Ukraine and Putinist met before for "peace talks", Ruzzia sent a wave of drones an missiles the day before. This is public knowledge. If you care to look at the footage of the planes destroyed, you will see that some of them had misiles loaded at that precise moment.
c) Ukraine has total right to target planes that are being used to launch missiles against Ukraine (or to detect Ukrainian planes in the case of the A-50s). If Ruzzia considers these are strategic assets linked to their ability to keep their nuclear deterrent, they should not use them against Ukraine.
Bottom line - if you use an strategic bomber in this war, the bomber is a target.
What in the world are you waiting for, Zelensky? You gave Russia a bloody nose and a black eye. Why have you stopped, now? You need to get in there and take them all the way out, before they have a chance to regroup. Especially if Trump admires your actions. Make him all-the-way proud of you.

Oh, do not worry BA, it takes some time to prepare the next 100 truck-delivered drones to the next objectives. Or a new submarine drone to hit a nuke sub - that would be costly, but I do not think the US would be happy about it.
Meanwhile, Ukraine bomb-sanctioned a Ruzzia high-ranking guy that was involved in the bombings of Mariupol. In this case, the delivery method was the gay man he was about to meet with. Not judging, just saying.
https://www.cbsnews.com/news/explosion-kills-russian-veteran-zaur-gurtsiev-airstrikes-ukraine/A retired Russian commander who led airstrikes on the Ukrainian port city of Mariupol died in a blast early Thursday in Stavropol in southern Russia, authorities said.
Zaur Gurtsiev, 34, received several medals for participating in Russia's grueling assaults on the cities of Mariupol and Avdiivka.
Authorities did not say what caused the explosion, but also did not rule out that Ukraine was responsible. Videos posted by Russian Telegram channels showed two men, one of them Gurtsiev, standing together in a residential neighborhood before a blast.
It is becoming difficult to escape warcrimes.
