One of the big misconceptions about the lights on the chanukiya, Chanukah Menorah is that they are to compensate for the shortness of winter days.
True, the Chanuka holiday occurs when daylight is shortest, and here in the Holy-Land it may rain, though very rarely snow. But we are forbidden to use the light for anything practical. It is not supposed to be the light for the room, or the street, or for reading, cooking or anything else one needs light.
The light of the chanukiya, Chanukah Menorah is to publicize the miracles that Gd performs for us, even more often than we may notice. Yes, specifically, on Chanukah, we celebrate the fact that time and time again, Gd is on our side. When the odds and the experts say that we're about to be defeated, such as when the powerful Ancient Greeks invaded our Holy land and forbade us to observe Judaism, we defeated them and returned Jewish worship to the Holy Temple.
Over the millennia, this has happened time and time, again. Also, please remember that the Modern Greeks aren't ruling and occupying the Holy Land any more. None of our ancient enemies exist today. They may have won many battles, but we, with the help of Gd, the One True Gd, have won the war.
