if we were invited there by the combatants that is a good thing, however if this is another coalition of the willing bla bla, I am not in favor of it at all. Look what happens when the United Nations, makes resolutions, and America behaves like an attack dog, invading places like Iraq. It often turns out we do more harm than good.
The best example is Iraq. The West believed the could just take over the oil and divided up among corporate groups, turning Iraq into an economic zone controlled by the west. Liberty was the excuse. As it turns out unfortunately, over one hundred thousand people have been liberated from their lives and the war goes on, because the western powers are not wanted there.
Unless some kind of a deal in brokered by the participants, and they need help controlling the peace, we should not interfere in the internal affairs of another country. The time the UN or other allies should become involved is when the conflicts spill over into nations next door. Civil wars should be allowed to come to a natural conclusion. To go in without an invitation is to plant yourself in the middle of a family fued.
The one place the world went in and did so correctly was in Afghanistan.
