Re: A little bit too late to matter
"again.. not provable."
It's called the preponderance of evidence. In the French election for example, the opponent Marine le Pen's party was bankrolled by Russian banks and parroting Russian friendly rhetoric. And then lo and behold a few days before the election, a phony leaked document purports to show Macrons hidden offshore accounts and Le Pen slanders him by repeating it. And then you have a twitter army reinforcing this message.
In Catalonia you have swarms of twitter bots and prominent Russian fronts like RT and Assange pushing separatist messages.
In Brexit you have UKIP employing Cambridge Analytica (where have I heard that name before?), and another Putin lover Farage popping up. All lovingly accompanied by swarms of twitter bots pushing anti immigration and other divisive messages.
And then you have the US where the microscope has demonstrated beyond doubt that Russia was involved.
A reasonable person would conclude Russian interference. And no, the "you too" argument is not a reasonable defence.
