The Navy Lark

In The Times today there is an opinion piece by Rear Admiral Chris Parry about the importance of NATO rather than the EU to the defence of the UK. Fair enough, but then we come to his concluding paragraph:

" Britain ( as England ) last achieved Brexit under Henry VIII. In declaring itself a sovereign nation, it threw off a corrupt, alien jurisdiction and faced down the military superpowers of the time. Our ancestors did not fear a " leap into the dark". Nor need we."

Oh dear, oh dear, oh dear me...

Where does one begin to deal with that little bundle of assumptions, and how long would it take?

Any jobs advertised for teaching History at the Royal Naval College in Dartmouth?
