If it was Judaism first, then aliyah would be the priority, but it's an organization of North American Orthodox Jewish Synagogues. And because of that, it's promoting the strengthening of some of its weaker communities. These are cities with all that an Orthodox community needs, but apparently, the population is getting older, smaller or both.
Many of us in Israel see this an another example of the defacto anti-Aliyah orientation of the OU. At least if Nefesh B'Nefesh was to be equally featured for those looking to move... someplace else.
