You really know nothing about Catholicism. Catholics ARE pro-Israel.
I was Catholic for six years, and I studied assiduously to understand my new faith. Finally I realized that nothing I could do would cause it to make sense to me.
As for the Church being pro-Israel, tell that to Michael Sabbah, Hilarion Capucci, the American bishops, Robert Sungenis, Nicholas Gruner, Pat Buchanan, Joe Sobran, the SSPX, the Feeneyites, etc.
