The “caravan” of Central Americans at the southern U.S. border seeking asylum has some conservatives wringing their hands about a Hispanic invasion. They should instead be asking what’s behind the destabilization of the countries these desperate migrants have fled.

Central American corruption, statism and crony capitalism have led to poverty and exclusion. The region’s classical liberals understand this connection and have fought to strengthen the rule of law. But their efforts have been undermined by the drug trade financing criminal networks that overwhelm institutions.

Now there is substantial evidence that a U.S.-funded fix for the problem in Guatemala, using a United Nations prosecutor, has itself been corrupted by unscrupulous actors and left-wing U.N. ideology.

As I wrote last month, the U.N. body is the International Commission on Impunity in Guatemala, or CICIG by its Spanish initials. It was established in 2006 with the best intentions to investigate the crimes of underworld networks. But the U.S. Helsinki Commission hearing on Capitol Hill last week revealed vile human-rights abuses by CICIG prosecutors in a case involving a family of Russian migrants—the Bitkovs. The case raises questions about whether CICIG has gone rogue.

That is unless you are one of many nongovernmental organizations and media operations working in Guatemala that are funded by George Soros’s Open Society Foundations and fellow travelers. In that case your instructions are to circle the wagons to defend CICIG prosecutor Iván Velásquez and destroy those who dare suggest that the case be judged on its merits.
