It's a load of bollocks, Froggy. "Kyiv will be ringed with tanks and howitzers within hours" – what? Was this written 5 days ago? This is what Putin probably thought would happen before the invasion, but clearly that's not what happened – in reality the Russian advance stalled, their logistics sucks and casualties horrific. They had more soldiers killed in 3 days of action in Ukraine than in the first 3 years in Afghanistan, it's totally unsustainable.
And to argue that Russians will weather the economic sanctions doesn't take into account the key factor that the war is so unpopular within Russia that their state TV
still cannot even admit that it's happening at all (I kid you not – they
report all the fighting is in Donbas in Eastern Ukraine), while almost every Russian celebrity, athlete and – unheard of – even 2 members of Russian Parliament publicly came out against it. Russians can endure economic suffering in service of a greater purpose – not as a result of a war that no one wants except the evil midget in charge. Over 200 of Russian POW's have already been captured by the Ukrainians and they all say the same thing – they have no idea what they are doing in Ukraine and they don't really want to fight. Putin is fucked.
