Regardless of one's Hashkafa - so many Jews are singing, dancing and rejoicing. how can one not be happy when so many Jews are happy???
So a little ואהבת לרעך כמוך and one is in a GREAT mood on Yom Yerushalayim. [One might also ponder the chesed of Hashem that we can live, learn, daven and breathe in ירושלים עיר קדשינו ותפארתנו].
