"...what a sham that was [Nostra Aetate]...."...during the Argentine dictatorship...." 

Nevertheless, Nostra Aetate has had a huge impact on Jewish-Catholic relations in the US, in US parishes, Catholic universities, and in academia in general. The major concerns of US Catholics and Jews today is to retrench the evils of anti-Semitism by the dialectics of (or reasoning in) dialogue and openness. On the other hand, only the zeal of bigots will multiply anti-Semitism by sentiments of prejudice, intolerance and hate (as we have seen  recently in Charlottesville, VA.). 
Finally, Francis's frequent addresses to Jews, re-echoing the teachings in Nostra Aetate and reaffirming the right of Israel to thrive, have endeared him to Jews today. His closeness to two Jewish Argentine rabbis only confirms this. Finally, only a dump pope would directly intervene in the Polish Church. It -- along with the German Church, Brazilian, and French Church -- are the most autonomous in the global church.
