Armies have very narrow fields of expertise. They are constituted exclusively for the purposes of killing people, threatening to kill people, giving the appearance that they could at any moment kill people, and supporting the efforts of those in their ranks whose specific mission it is to kill people.

A peacekeeping mission is a mission in which an army makes its presence known and drags behind it an explicit threat that if anyone gets out of line they will start killing people in a manner far more efficient and professional that any of the locals could hope to aspire to.
Historically, armies are bad at governance.
