It was NOT "the allied nations who had come to agreement at the Arcadia

The Arcadia Conference also produced the Declaration by the United Nations.
Devised by Roosevelt, the term "United Nations" became the *official name*
for the Allies. Initially signed by 26 nations, the declaration called
for the signatories to uphold the Atlantic Charter, employ all their
resources against the Axis, and forbade nations from signing a separate
peace with Germany or Japan.

Therefore the Normandy invasion was an action by the armed forces of
some of, but not all, of the United Nations.

Today, just because not every nation contributes soldiers to UN peace
keep missions, and they just contain say troops from Turkey and Fiji,
you do not argue that they are not UN actions.

Your problem is you are holding to post-1945 persepectives on the nature
of the United Nations Organisation. The United Nations pre-1945 had no
headquarters or secretary general.

The Axis powers had no headquarters or secretary general, but the allied
forces of the United Nations were fighting the forces of the Axis powers
when they landed on the beaches of Normandy.

To have been a "United Nations" invasion the invasion would have had
to have been authorised by that group as a whole, which it wasn't.

No, not at all. You are applying post-1945 of what constitutes the
United Nations Organisation today. The United Nations pre-1945 were
authorised to do whatever the USA and UKofGB&NI decided, perhaps with
the approval of the USSR.

WW2 was not a democracy but a power struggle, even amongst the allied
nations.

How difficult is that to understand?
