Power-grabbers who want something wage war to get what they want. If the power-grabber is, to some degree, dependent upon public support for the action, the the power-grabber would be inclined to use any type of argument that helps the power-grabber achieve his or her goals--that could mean using utilitarian arguments or rights-based (deontological) arguments.
Perhaps your question was whether the "pure" version of utilitarian philosophy (which doen't exist) would compel somebody to support a given war. My answer is similar to the above: the "science" of utilitarianism is strongly affected by the values that people use to determine what is good, so a room with 20 utilitarians could give you 20 different answers on the validity of any given war. That being said, I would say that utilitarian philosophy allows for a war if that war is the best way to maximize happiness or minimize suffering according to the values of the utilitarians. There could even be utilitarian philosophers who fight each other over what they thing is the best course of action.
As a somewhat post-modern philosopher, I doubt that our perception of what is good is objective---meaning that just because I think some particular social or economic outcome would be good does not mean that it actually would be good. I prefer a something like this:

General recognition of the exclusive sovereignty of each party over its lands, people, and agents abroad, and each and several responsibility for the warlike acts of any of its citizens or agents.
the general idea being that each country would be left with minimal threat of interference from other countries.
