UN missions, they believed, could and would bring peace to the world's conflict zones.
UNTSO und UNMOGIP are still ongoing, but neither of these UN missions has brought lasting peace.
"Some members of the UN Security Council have the feeling that UN missions are too expensive and achieve too little," says Jaïr van der Lijn, a senior researcher at SIPRI, the Stockholm International Peace Research Institute, "which is why they want to reduce the budget for peacekeeping missions, with the Trump administration leading the way."
It is a trend that continues today, SIPRI's van der Lijn tells DW: "While there has been a steep decrease in the number taking part in peacekeeping missions, the numbers deployed in non-peacekeeping missions has actually risen - above all inanti-terror operations."
This is the case inMali, where a UN mission called MINUSMA is tasked with monitoring a fragile peace accord and, at the same time, guaranteeing the security of the civilian population.
