Evidence is somewhat different to proof because, oh never mind.
As noted in other posts, twice Schwab has publicly stated Putin's one of his own charges. Neither Putin nor the Kremlin has denied the claim, which might suggest it's true, and just last year no other than Bad Vlad himself was the keynote speaker at the WEF's annual shindig at Davos.
But anyway, not that any of it will matter to the like of you and I as we will be preoccupied with trying to survive the desperation and lawlessness that will envelop during societal breakdown, whether that's post mushroom clouds appearing on the horizon or following the purchasing power of everyone's savings and income being reduced to precisely sod all due to hyperinflation.
