Chanukah

What is Chanuka really all about? Does it revolve around the miracle of the oil lasting for 8 days instead of just 1?

Is the minhag of some women to curtail work on Chanuka binding? When exactly does it apply, and what type of work is included?

The holiday of Hanuka commemorates both military and spiritual victories, of a national nature, during the Second Temple period. On the one hand, the one-day supply of oil in the Holy Temple miraculously lasted for eight days. On the other hand, the greatly outnumbered Jews also won incredible military victories over their Greek enemies, thus preserving the State of Judea for over 200 years. The war was fought also against the Hellenists [Greek sympathizers, mostly Jews], who sought to secularize the Jewish Nation. Do the Hellenists of then have a parallel today?

What did the Maccabim do when they found that 1 jar of unblemished oil? Did they put all the oil in the Menora at one time, so at least 1 day would be a "pure" & complete Mitzva? Or did they divide up the jar & place 1/8 of the oil in the Menora each night, so as to at least do some of the Mitzva?

Is Hannuka a religious holiday, on which the Nation of Israel commemorates its religious victory over Greek paganism? Or is it a national holiday, celebrating our military defeat of Greek expansionism in the Land of Israel?
