That's not strictly true. On the short end, there was the six-day war. On the long end, there was the hundred years' war.

Putin was clearly aiming for the short option, but then I suppose most belligerents usually are.

And Russia expected their little venture to be done in days.

Frontlines were actually moving, especially in the Eastern Front. Not so much in China and the Pacific, though.

We can hope Putin dies from being an old fuck and Russia gives up

That's because it isn't really about any particular military objective, it's about creating business for the war industry.
