Whereas Nostra Aetate seems actually ambiguous about the status of Jews, there is no such ambiguity concerning Islam!

...The apostle Paul maintains that the Jews remain very dear to God for the sake of the patriarchs since God does not take back the gifts he bestowed or the choice he made...
...lt is true that the Church is the new people of God, yet the Jews should not be spoken of as rejected or accursed as if this followed from holy Scripture...
...The Church has also a high regard for the Muslims. They worship God, who is one, living and subsistent, merciful and almighty, the Creator of heaven and earth,[1] who has also spoken to men. They strive to submit themselves without reserve to the bidden decrees of God, just as Abraham submitted himself to God’s plan, to whose faith Muslims eagerly link their own. Although not acknowledging him as God, they worship Jesus as a prophet, his virgin Mother they also honor, and even at times devoutly invoke. Further, they await the day of judgment and the reward of God following the resurrection of the dead. For this reason they highly esteem an upright life and worship God, especially by way of prayer, almsdeeds and fasting.
Over the centuries many quarrels and dissensions have arisen between Christians and Muslims. The sacred Council now pleads with all to forget the past, and urges that a sincere effort be made to achieve mutual understanding; for the benefit of all men, let them together preserve and promote peace, liberty, social justice and moral values...
I see no ambiguity in this statement.
Not ambiguous? Let's take a look.

Again, note the characteristic omission. Christianity teaches that the one God revealed Himself more fully in the New Testament as consisting of three persons, Father, Son, and Holy Ghost. The Son (also called the Word) was born to the Virgin Mary with a fully human nature alongside His divine nature.

The most significant quarrel is over the nature of Christ and the Council is scarcely authorized to give that up.
