Well, it's certainly an interesting development. We're still talking fairly small forces, at most a brigade but some reports are saying just a battalion, so still looking more like raid than an invasion, just a bigger raid with more serious firepower.

That said, I had already been thinking for a while that taking the war across the border does seem like a good way for Ukraine to try and break the stalemate in their favor. I wonder if the reason they've been avoiding doing that is not just optics, but western limitations on the use of their weapons.

I have no idea how realistic it would be logistically, but on a concept level, going around the Russian defenses insteof through them just looks like an obvious move, especially when it would mean taking the fight to the enemy's side of the border.

In any case, those western limitations will look even harder to justify in a situation where battles are happening fully on the Russian side of the border.

This should also force Russians to start properly defending their side of the border instead of piling all their resources into Ukraine... but that's been said before and it didn't happen then so who knows.

Maybe Kursk will hold a referendum to join Ukraine.
