Sister Lucy has written that this imperfect act of obedience, while not fulfilling Our Lady's Fatima request, nevertheless hastened the end of the Second World War, thus sparing the lives of tens of millions of souls. And then on August 29, 1989, Sr. Lucia affirms in correspondence that the consecration "has been accomplished" and that "God will keep His word." This is borne out by the timeline of events posted above.
The above timeline is a strawman. Russia has not converted to Catholicism and "a period of peace" has yet been granted to mankind; just look at the Christians being persecuted in muslim countries today. Look at mothers, including Catholic mothers, butchering their own babies while still in the womb.
As far at the so-called "correspondence" in 1989, your link is broken. I wonder why that happened?
Here's a link that works:
