I believe it was an imperfect consecration, like all the rest. As was made clear to me after erroneously thinking it was "good enough." It wasn't.
He did not order the bishops to perform it in union with him, as it was a consecration done by Pius XII himself in a letter. The "peoples of Russia" clause probably came from the political climate of the era (not really unlike our own today), and a weakness on his part to just go through with it. It could even be seen as providential in the fact that he wasn't doing it according to the request of Our Lady anyway.
Lad posted in one of the other threads the quotes of Our Lady on the consecration itself:
Our Lady to Sister Lucia at Tuy, 1929:
Quote
Then Our Lady said to me: “ The moment has come when God asks the Holy Father to make, in union with all the bishops of the world, the consecration of Russia to My Immaculate Heart, promising to save it by this means.”
“ So numerous are the souls that the justice of God condemns for sins committed against Me, that I come to ask for reparation. Sacrifice yourself for this intention and pray.”
Sister Lucia elaborated in 1930:
Quote
The good Lord promises to end the persecution in Russia, if the Holy Father will himself make a solemn act of reparation and consecration of Russia to the Sacred Hearts of Jesus and Mary, as well as ordering all the bishops of the Catholic world to do the same.
As you can see, Pius XII did no consecration in union with
all the bishops of the world, and did not
order them to do so. And he did not exclusively consecrate Russia itself, but the "peoples of Russia".
In all honesty, this consecration should've been done when it was requested as it would have been
extremely easy for Pope Pius XI or Pius XII to command the bishops to do so on a set date at a set time to say a prayer that doesn't need to be much more than a paragraph-long statement.
God gives us such simple things to do, and because of original sin we bungle it all up.
