So why won't he do it?

That is the million dollar question. Pope Pius XII performed a consecration of Russia but all the bishops of the world did not participate (I don't know why). His partial consecration is believed to have obtained graces which ended WWII.

One of many rumors about Pope John Paul I is that he was preparing to do the consecration before he was, um, removed from this world. Sister Lucy herself met with him privately when he visited Fatima as the Archbishop of Venice. She must have known he would be the next Pope.
