Got a really fucking shitty attitude
Was it ever proved that negotiators were poisoned. Even the Ukrainians don't seem to have pursued that line.They're poisoned people who were sent as negotiators. The Russian government currently sees attempts at diplomacy as a sign of weakness. Unless and until that changes, any attempts at diplomacy will be miserable failures.
It's not like this is a case of the Russian government having an off day, either. They've been salami-slicing their Ukrainian neighbours' territory since at least 2014. This is a consistent pattern of behaviour.
The idea of diplomacy is to offer incentives for Russia to change that line, however that may be done.
Yes, it has been going on since 2014. That's when Russia warned that it will not tolerate Ukraine joining NATO. The Minsk agreement wasn't pursued vigorously enough.
