use peacekeeping in a sentence.
As a tax payer, I'm not too happy about paying for these peacekeeping/war adventures in the M/E.
Thing is, what you describe ("Merely installing a peacekeeping force, and then concentrating on the reconstruction of those countries -- the building of schools and hospitals, and other infrastructure") is precisely what did happen in the DR Congo and Sudan.
In neither case was the peacekeeping mission itself particularly successful.
These conflicts are usually just too much of an intractable problem for peacekeeping to be of any real effect.
Soldiers serving in the former Yugoslavia in peacekeeping used their personal mobile phones to communicate - more reliable and more secure than the issued kit.
In that case you accept no possibility of a defensive or peacekeeping force working on behalf of ordinary people and think that soldiers are mindless thugs who will just loot anyone they are sent to protect.
If our governments couldn't field the army unjustly, our peacekeeping might not only be welcome but might finally work.
