"the Russians would carpet bomb the nation with their version of the story"

But how can they carpet bomb the US with fake news from Russia?

"Even in Europe"

Maybe Europe will have to shake off its arrogance and realize how much they have always depended on the US. I say that as an European - and here, also, people are divided over Trump, just as in the US. There are elections in Germany this year (if you meant Germany), although to be fair, no major shakeup is to be expected. But that is only for lack of an alternative, there is no Trump here to vote for. But maybe some adjustment of policies will occur before the election date, anyway.

"Yes, but just like Hitler found out: you can't fight wars on all fronts at once."

Still, making a tactical error is not in itself evil. And chaos is a tactic that sometimes works. It won him the election already.
