Not wanting to make this political, but one could say the same about the current US president. Based on his social media output it seemed he was downright batshit insane when he got elected (some might say even still, although he seems to have calmed down a bit). He seems to be achieving things though and we didn't end up with WW3 as a lot of people predicted.

Perhaps the world needs these crazy people occasionally to come in and stir up the pot?

(Don't get me wrong, I'm not a fan of the guy and not being from the US my opinion doesn't really matter, but thought I'd give me $0.02 so to speak)
