As Ukraine is under military assault by Russia at the moment, they should abandon any complaint monitoring for the time being.
That turns out not to be the case. The Ukrainian army - which is rapidly running out of effectives who are willing to lay down their lives for billionaire Nazi oligarchs - has been severely mauled by the militias formed to defend the area around Donetsk and Lugansk. As Americans would form militias to fight for their homes if an army trundled into their state and began bombarding city centres.
Turns out? Turns out?
The legal government led by the newly democratically elected president of the Ukraine was winning and driving the rebels out of even their stongholds like Luhansk, before the Russians decided to openly intervene instead of just sending "soldiers on holliday" and anti-maylasia air systems.
Now, as in the latest few days the Ukraines are withdrawing, they havn't lost any engagements yet, but are moving to better prositions and waiting for international reactions before engaging the invading Russian troops.
