Do you know what happened last time Ukraine had an agreement with Russia and USA?
Why would they make the same mistake?
Why are you pressing for that as it is it a valid option? Why are you ignoring what Russia and the USA did not so long ago? Are you of the opinion that trump can bring peace to Ukraine quickly?
Why are you so opposed to giving free money to Ukraine?
My point is that history shows it's not really wise to negotiate, or go for treaties or agreements with Russia.
Whilst strategically it would be good to make the war stop it would only be a temporary and remedial solution not really solving the root cause of the problem.
So why do it?
