Uganda ping.
For those who need a quick primer the LRA is a murderous death cult who at times claim to be Christian and at times don't. They began in Uganda but move between Uganda, South Sudan, Central African Republic (CAR) and Democratic Republic of Congo (DRC). They are supported by the government of Sudan.
They don't die easily. In 2006 the UN sent Guatemalan special forces in DRC who were experienced jungle fighters. The Guatemalans lost eight soldiers in an ambush and pulled out of the country.
In 2011 the US sent in 100 “advisers” based in the city of Obo in south eastern CAR. This gave them a central location to operate in all four countries. This mission was approved by Congress overwhelmingly.
In 2013 Muslim rebels overran the capital of CAR throwing the country into chaos and leaving our troops in limbo. The pentagon was none too clear on if they were still in CAR or had moved to Uganda or elsewhere.
Recently South Sudan had teetered on the brink of plunging back into civil war. This gives Kony and his men another country where they can operate with almost no chance of detection because the government can't spend any time or resources looking for them.
