The missing comma.

 A country that presents itself falsely is not to be trusted.
(Well, no country, except perhaps San Marino can be trusted)

The United Kingdom of Great Britain and Northern Ireland
is a masquerade, a false representation
because the Kingdom of Ireland
(of which the present Northern Ireland
is a fragment) ceased to exist in 1800.

In 1922 most of Ireland bloodily seceded from the United Kingdom, leaving an entity, curiously named Northern Ireland
and not North Ireland (like, say, North Korea, North Macedonia,
or South Sudan) officially, practically, legislatively
closer to the UK than the Isle of Man or the Channel Islands
(which are a lordship and dependencies respectively)
but a separate entity which will eventually secede.  

So the UK's proper title should contain a comma,
or, better, a dash:
the United Kingdom of Great Britain - and Northern Ireland
trailing in its abominable, royal footsteps.
