Can you give the sources for saying Hallel on Yom Haatzmaut with or without a Bracha? I have been saying it all my life because that is what my father A"H taught me to do. I now have children to whom I want to teach this and I find that I cannot give sources for this practice. Thanks.

HaRav Dr. Nahum Rakover's book on the Laws of Yom HaAtzmaut and Yom Yerushalayim is an anthology of articles dealing extensively with this issue.
