There was a peace deal back in May, but Boris Johnson(on behalf of Biden/Nato)told Zelensky to scuttle it in exchange for lots more money and more arms.
Ukrainian's are losing the war, with no hope of ever regaining lost territory.
Ukraine will likely lose Odessa and the entire black sea coast soon, becoming landlocked, unless Ukraine negotiates a settlement before then.
As such, more and more Ukranians will be eager to cut their losses now and negotiate a settlement, if Biden/NATO permit them to do so this time around.
