War is worse than Hell. Cue the scene from M.A.S.H.
When this started, I felt my heart breaking. Not just because I knew there would be devastation and destruction of the towns and villages. Not because I knew there would be civilian casualties. And not because I knew it would be revealed that the Russians and their mercenaries would end up brutalizing and committing war crimes upon civilians. But also because I knew the suffering won't stop after the Russians leave. Surviving Ukrainians will in turn brutalize those neighbors they thought were sympathizers of the Russians. Doesn't matter if that person was forced at gunpoint to help the Russian army. When you have a brutalized and devastated population, they will look at any reason to enact revenge and seek what they feel is justice, especially those who they think are traitors.
It doesn't stop there either. Even after all of that stops, the nightmares will haunt these people for a generation. Those are the reasons I have been so moved by all of this. I saw it all firsthand in Bosnia, so I knew what was going to happen, even if our media is acting shocked and surprised. It's what happens in every war.
It would be a huge mistake, IMO, to underestimate the Russian army fighting capability. This disaster (militarily speaking) for them was because they thought it would be a cakewalk. That led to a lack of logistical efforts in place to sustain a longer invasion. And the average soldier had no idea what they were doing at first, causing morale issues and lack of organization.
Many of those issues have been addressed. Russia pulled back and consolidated in other areas for a second attack. This second attack will be more effective for them. Putin brought in additional mercenaries who are more experienced than the original conscripts. I'm not saying they will take over Ukraine, but I suspect there will be a second offensive, and it will be much worse for the Ukrainians than the first was.
