War is always devastating.

I doubt the Ukraine/Russia situation is politics only. When so, Ukraine fighters would not give such high resistance.

In my book: Freedom is the most important. Sometimes one has to fight for it. If Ukraine would stop fighting, Russia will take over the entire country. We all know what freedom means in Russia. By law, one can (and likely will) go to prison for decades when voicing something that is not backed by Russian state-controlled news agencies. I donno what you are accustomed to in your country, but freedom of speech is something that is highly important for a prosperous society. Interestingly, I've seen a few different interviews with peeps in the Krim. Those living there and voted for Russia back in 2014, now saying: I wish I never done that. Since it's just a few handfuls of peeps in these docu's, I can't tell if this is a general sentiment, or careful moderated hence I don't make conclusions. However, knowing the work by these peeps creating these docu's, I give the content a high-quality mark.

They should force negotiations and send humanitarian aid instead of weapons

This is not happening in your view? In my view, this is happening big time. It's for a reason why so many politicians are having almost daily calls with the leaders of both countries.

Tg channels

Euhm, do you have access to these? Are those that don't have access to these Telegram channels in Ukraine or also in your country? Interestingly, the founders/owners of Telegram had to leave Russia since otherwise, they would've ended up in jail. They didn't want to play ball with the state/KGB, sharing all information with them. It's for a reason why the servers of Telegram are not in Russia, but in Europe. Anyways, just an interesting observation.
