There are people who only pray that the generation should return and repent. This is not proper because it arouse the Midas HaDin the attribute of Divine strict justice, G-d forbid. The proper approach is to evoke wonders and miracles for the sake of Israel. Then the Jews will repent out of love because of the miracles. This is what happened at the time of Mordechai and Esther as it says in Talmud tractate Shabbos 88a they fulfilled what they had already accepted. This is also the meaning of the verse in Micha 7:15 As in the days of your exodus from Egypt I will show him wonders.
