However, let's talk realpolitik.
Ukraine innovates and Russia copies/addapts. Russia has ALWAYS been good at this game. Russia reminds me so much of the roman military in this sense, extremely good at copying and incorporating foreign military tactics/equipment.
Think of the initial long convoys ukraine destroyed, the bayraktars -- Russia addapted, the then the brilliant Eastern campaign where Ukraine managed to route the russians -- Russia adapted, that stopped working, then the indiscriminate massive artilery strikes Russia was doing -- ukraine started using better western artilery and himars, stopped the russians but the russians also addapted spread their logistics and so on; then the drones -- russia copied those even innovated with fiberoptic drones, then the Shaheds, ukraine adapted with fpv interceptors, then Russia started using jet powered interceptors, balistic missiles -- Ukraine initially stunned the world with Patriot interceptors but Russia kept firing until Ukraine ran out of interceptors, then the USV -- Ukraine had and still has great success with them, but look, Russia started using USVs also and Ukraine has no response to those.
It looks like the end will be decided by the country who just has more resources and willpower to continue.
I'm seriously scared for the next years -- the US is clearly turning hostile to Ukraine, Europe is turing far right with russian puppets everywhere.
I think more precise language is important here. It is my perception that a small faction that currently controls the federal US government is hostile to Ukraine. A large majority of the general population of the US seems to support Ukraine.
You might argue that this distinction doesn't change the reality for Ukraine's prospects, but I disagree. The small anti-Ukraine faction in the US is becoming increasingly unpopular within the US. It is doubtful its dominance of the US executive branch will survive the next general election in two years. Its total control of the US government may not survive another month.
The willpower of Ukraine has been underestimated throughout this conflict. It seems a cinch it will hold strong for three more weeks. Then the US campaign for President begins in earnest and it would not be surprising for many US politicians to press against the anti-Ukraine faction in a bid for control of the US Presidency. The US Congress may try to remove itself from under the thumb of the current president and you might see sweeping changes in as little as three months. Or you might not.
Take courage. I think Ukraine's resolution to survive will outlast the influence of Putin fans who happen to have an outsized influence in US politics at the moment.
“61% of Americans sympathize more with Ukraine, compared to only 3% who sympathize more with Russia; 22% who take neither side” [1]. (45% of MAGA supporters, 63% of GOP.)

Russia can stop the war (and thus sanctions) whenever they choose to. Ukraine does not have that option.
Second, EU and US were not signatories to any deal between Russia and Ukraine, so any sanction relief was never on the table as part of the grain deal. Russia may have asked for it, but it was not offered or implied in any way by anybody. And yes, this is typically how deals work everywhere.
Third, any ship that Ukraine sinks is 100% on Russia because they’re the reason any ships need to be sunk in the first place. Again, Russia could stop the war today and no further violence would be necessary.
Nothing. Your master did with his 3 day invasion.
