I should not even engage in this conversation as it is so old hat as to elicit a yawn…but I have to point out halachic misrepresentations- all you have to do is quote gemoro megillah 14a on the saying of hallel on any occasion that the jews are saved from destruction. Whether you like yom ha=atsmaut or not, you must be totally blind (you too, apokerma) to deny that the Jews of Eretz Yisroel were facing destruction in 1948.(and you cannot even use the answer that you don’t say hallel on a miracle in chutz lo-oretz!)
Secondly, it is totally ridiculous to deny that we celebrate the military victories. Have the critics even READ “bimei matishohu ben jochanan kohen godol”? Of course, we celebrate military victories! Have you ever read parshas Masai- the war on midian,parshas beshalach- the war on amolek? From time immemorial, we had armies and military victories that were celebrated (look in tenach).
