"So do you think Russia invaded in 2022, not intending to be victorious in the war?
Also, as an aside, I notice you made no comment on the main thrust of his post, including his assertion that Russia will use nuclear weapons"
I suppose it depends on what you call an Invasion, there were Russian troops on Ukranian territory covertly assisting pro Russian separatists before tanks rolled over the border.
As for the use of nukes, , again, it depends on what Putin's motives are - some say he just wanted to install a puppet regime, like he's got in Belarus and re-create the territory of the former USSR. Others say he's after rare earth metals, which, it is said, Ukraine has a lot of. I would suggest that in either case, the use of nuclear Weapons, even small ones would be a bit of an own goal - who wants land that's unusable for years?
