Nostra Aetate was published more than 46 years ago. It is fairly short and well footnoted to the Bible. Here are important (IMHO) excerpts:
God made the whole human race . . . His saving design extend to all men . . .
The Catholic Church rejects nothing that is true and holy in these religions. . . .
[Unstated is rejection of what is NOT true and holy.]
Indeed, she proclaims, and ever must proclaim Christ is “the way, the truth, and the life” (John 14:6), in whom men may find the fullness of religious life, in whom God has reconciled all things to Himself.* [Underline is mine]*
Since in the course of centuries not a few quarrels and hostilities have arisen between Christians and Moslems, this sacred synod urges all to forget the past and to work sincerely for mutual understanding and to preserve as well as to promote together for the benefit of all mankind social justice and moral welfare, as well as peace and freedom.* [understanding is not the same as presuming equality of thinking]*
We cannot truly call on God, the Father of all, if we refuse to treat in a brotherly way any man, created as he is in the image of God. Man’s relation to God the Father and his relation to men his brothers are so linked together that Scripture says: “He who does not love does not know God” (1 John 4:8).
The Church reproves, as foreign to the mind of Christ, any discrimination against men or harassment of them because of their race, color, condition of life, or religion. On the contrary, following in the footsteps of the holy Apostles Peter and Paul, this sacred synod ardently implores the Christian faithful to “maintain good fellowship among the nations” (1 Peter 2:12), and, if possible, to live for their part in peace with all men, so that they may truly be sons of the Father who is in heaven.
All this reads as solid Catholic teaching to my eyes.
