It isn’t a matter of controlling God; it has more to do with doing what He says and trusting that He will keep His promises.
Sister Lucia, the Fatima seer you mentioned, quoted our lady as saying in 1929:
"The moment has come in which God asks the Holy Father, in union with all the Bishops of the world, to make the consecration of Russia to my Immaculate Heart, promising to save it by this means."
You can read the Pope’s consecration prayer
here (it starts with “O Mother of all men” and ends with “light of Hope”). It is a beautiful prayer, but it does not mention Russia at all!
After a similar consecration of the whole world in 1942,
Sister Lucia said that that was not what Our Lady asked for:
“The exact petition of Our Lady was for the Holy Father to make the Consecration of Russia to Her Immaculate Heart, commanding that at the same time and in union with His Holiness, all the bishops of the Catholic world should do it.”
It seems odd that consecrating the whole world rather than specifically Russia would be inadequate in 1942 but satisfactory in 1984.
(I am also doubtful that some of our more progressive prelates would have bothered to join the Holy Father in praying for Russia, even if he had done so, especially if their prayers were merely requested or assumed, rather than being commanded.)
