BS”D
It is PRECISELY because the army (and the medine which is behind it) have no intrinsic kedusha that its success depends on our Torah so that Hashem sees that we TRULY deserve ERETZ YISROEL under malchus beis Dovid!
That is why we DO need to put on tefillin with soldiers, send them sifrei Torah, learn in their merit and in the merit of the Jews whom they are physically defending.
And B”H so far, compared to the last military action, bnei Yisroel are way ahead. Let this be the very end of all wars and let the klipa of Hamas disappear for all time while the klipa of Zionism is replaced with the ultimate kedusha of Moshiach!
