It has never been proven as you claim.He's a senile old man with no grasp on reality, but hey, at least he's not Donald Trump that's all that matters eh.
He reminds me of Nicola Sturgeon in Scotland - to hell with consequences and ignore what works/what's good for us provided we aren't aligned with England, that's all that matters. Ruin the country out of spite.

That's the problem. In a nutshell.
That is the problem.
