what happened to the Northern Shomron?

No one talks about the Northern Shomron (NS). Everyone is talking about Gush Katif (GK). Why?

There are more people in GK than in NS, but I don't think that's the reason. My gut feeling is that precisely because GK is less integrally part of Eretz Yisrael than NS, the focus is on GK. In other words, by focusing on GK, the anti-disengagement movement is saying "we are opposed to giving up any part of Eretz Yisrael - look how much we fight for GK."

But bottom line, NS is much more important, even if there are less yishuvim. They are the heartland of the country. I'm concerned that by not putting a real fight there, if as likely the pullout goes through as planned, it will be much easier to pull out of small sections of Yehuda and Shomron.

But I haven't heard anyone say that NS is more important than GK. Is it too late?
