For starters: it was a Nazi salute, let’s not even try and pretend it was anything other than that.
That therefore leaves, in my mind, two possibilities:
- He did it not because he is fully aligned with Nazism, but because he wanted to rile his opponents.
- He did it because he is revealing his true colours as a Nazi.
Though possibility one is (possibly) more palatable, what does it say about someone that they would choose to align with something so horrific to rile their opponents?
So, all told, there is nothing good that can be gleamed from what he did.
And this is the person who has the ear of the man with the most power in the world.
