I was not talking about the details as you enumerate - just that there is one. No one is going to announce the details of a plan such as that to the enemy or to the public at large. There is a plan - you fill in the blanks that you see fit.
In the Second World War everyone knew that Europe was our first priority, that there would an amphibious landing in France at some point and that our goal, as expressed by Pres. Roosevelt and PM Churchill together in January 1942 (Casablanca), was the Axis powers' "Unconditional Surrender".
That's leadership.
That's a goal.
That's strategy.
It's even a bit of operational planning known by the public, though of course details on D-Day were a closely guarded secret, surrounded, as Churchill said, "by a bodyguard of lies".
