She's talking about the UN Peacekeepers, which is its own department started in 1958. Having done a lot of reading on them lately it looks like their primary function is to provide jobs for third world soldiers from places like Bangladesh (8,826), Pakistan (8,251) and Ethiopia (6,514). Oh, and they must have a whole section that does nothing but make up acronyms.
I cede the department, but the article still comes across as though the UN as a whole is venturing into new territory. Interesting stuff though.
