Collective punishment IS a war crime. Travel is a privelege, not being able to go on holiday to specific places isn’t punishment. Do you realise most countries aren’t permitted to travel somewhere?
It’s not about traveling, and not about Russians at all. I just gave an example. Look,
Ursula von der Leyen was against Russians destroying the energy infrastructure of Ukraine.
The same Ursula supports energy blockade of Gaza by Israel.
It’s just pure hypocracy.
In both cases the civilian population suffers the most. In both cases it’s a war crime and should be condemned.
