The same place he gets all his "facts". Lala-land mostly. Having not
been in the Navy. I've no idea of what the proportion is, but I'd guess
it's about the same as the general population.

Would he like to explain?

Probably not. He'd rather go off at tangents, hurl abuse or get tetchy
over one small point. As per usual in the Chris Stevens "way".
