It is universally accurate in as much as "et al" is not necessarily universal... which it seems you have not realized,
or have ignored.

Having said that, just so there is no
possibility of misunderstanding,
imho there have been leaders of the USA that deserve admiration and respect.

However, even though many have the popular misconception that the Crown is just a figure head;
in 1975 the Crown fired the then Prime Minister of Australia, and appointed the leader of
the opposing Liberal Party, Malcom Frazer as "caretaker" Prime Minister... long story short, because of
an untenable situation.
The Crown also declared that an Australia wide general election
for Prime Minister take place soonest.
Malcom Frazer won the election by a landslide.

The action by the Crown was both pragmatic and brilliant.

The population of the "Commonwealth" countries is over 2 billion souls... and Queen Elizabeth,
during her impeccable reign of over 70 years, has earned the admiration, respect, and love of most of those subjects.

Apart from that, more than 700,000 trained Commonwealth soldiers, alive today, have signed the
"Bloody Oath"... ie. if the Queen says jump, they jump, and don't come down until Ma'am says so.

Despite that profound power, Queen Elizabeth has proved herself a Ruler of epic and outstanding virtue.

I present the above examples to demonstrate that the Crown
is far far more than a "figure head".

Her son Prince Phillip has had the greatest mentor a man can have, so no doubt he and his children
will follow in HRHs footsteps.
