“Stop with your Zionist lies! Even if there is a Mitzvah to conquer EY nowadays, the Israeli govt. & the IDF aren’t doing it. The proof is they gave up S. Lebanon & GAZA & the West Bank! “
I’m not commenting on the Medina or Tzahal, but there are many reasons within halacha that could explain giving up land. For example, what is out chiyuv today? Is is conquering or inheriting (see Ramban at end of Rambam’s sefer Hamitsvot)? Does pikuah nefesh override?
