In my opinion there are 3 American holidays that Jews should observe: THanksgiving, Mother’s DAy, and FAther’s Day.
Grada,
Is there any reason your list did not include Independence Day, Memorial Day and Veterans Day?
I would think that we should have a great deal of HaKaras HaTov for the opportunity that we have here in the United States to live our lives according to the dictates of the Torah as, perhaps, never before in the long history of our exile.
And, likewise, I would think you would want to honor those who died to help secure that freedom for you and honor those living veterans who have worked towards those same goals.
