You really had to look up Banderites?
I shouldn't be surprised. Unfortunately there's a lot of people who don't know the fascist history and how plenty they still adore this genocidal nazi. Not something the western press writes about bcs 'no nazis in ukraine".

And here's the daily OSCE report from 1 day before Russia intervened:

In Donetsk region, between the evenings of 18 and 20 February, the SMM recorded 2,158 ceasefire violations, including 1,100 explosions (144 outgoing, 19 airbursts, 37 impacts and 900 undetermined). The majority of ceasefire violations were recorded on the morning of 19 February in areas east, east-south-east, and south-east of Svitlodarsk (government-controlled, 57km north-east of Donetsk)

In Luhansk region, between the evenings of 18 and 20 February, the SMM recorded 1,073 ceasefire violations, including 926 explosions (112 outgoing, 44 impacts and 770 undetermined). The majority of ceasefire violations were recorded in areas close to the disengagement area near Stanytsia Luhanska (government-controlled, 16km north-east of Luhansk)

The hostilities had massively increased showing the Banderites were ready to do an offensive to finally genocide the ethnic Russians which their PM called SUBHUMANS in true nazi style.

And if there are germans celebrating Hitler, then yes I would certainly hate them too.
