Amid rapidly deteriorating relations between the US and Mexico, reports are emerging that President Donald Trump openly threatened military intervention in a phone call with his counterpart Enrique Peña Nieto. According to a partial transcript of the conversation obtained by the Associated Press, Trump told Peña Nieto: "You have a bunch of bad hombres down there. You aren't doing enough to stop them. I think your military is scared. Our military isn't, so I just might send them down to take care of it." ("Bad hombres" is a term Trump also used in his final debate during the presidential campaign to refer to Mexican narco-gangs.)

The Philippines' ultra-hardline President Rodrigo Duterte may have finally gone too far. It is all too telling that after his anti-drug crackdown has claimed perhaps 7,000 lives since he took power last June, it is the death of a prominent foreign businessman that has finally prompted him to—perhaps—rein in his murderous police. All those suspected low-level drug users and dealers who were killed? Their lives don't matter, apparently. But after rogue National Police officers abducted and put to death a South Korean shipping company executive, Duterte has finally pledged to disband the controversial anti-drug units.

The planned meeting in Washington between President Trump and his Mexican counterpart, Enrique Peña Nieto, was called off after Trump signed his Jan. 25 executive order decreeing construction of a wall on the border—accompanied with more bluster about how Mexico will pay for it. Since the cancelation, Trump and Peña Nieto have engaged in an unseemly Twitter war, each taking responsibility for calling off the meeting. Things got worse when the White House raised the option of making Mexico pay for the wall with a 20% tariff on all goods coming in from our southern neighbor. The threat portends a trade war with the United States' third biggest trading partner.

Argentina's new restrictive immigration policy is drawing protests from neighboring Bolivia—and accusations that President Mauricio Macri is emulating Donald Trump. Macri's Decree 70/2017, issued late last month, modifies Argentina's Immigration Law, barring entry to those who fail to report criminal records to immigration authorities where offenses concerning drugs, arms trafficking or terrorism are involved. In issuing the decree, Macri claimed that a third of inmates in Agrnetina's federal prison system are foreginers, and said the country faces "a critical situation that warrants urgent measures." Bolivia's President Evo Morales noted that Macri's decree immediately followed Trump's executive order barring entry to the US for nationals from seven Muslim-majority countries. Morales sent a delegation to Argentina led by José Alberto Gonzáles, president of the Bolivian Senate, to meet with Argentine officials on the question.

Guy Philippe, a former paramilitary boss and coup leader who was elected to Haiti's Senate in November, was arrested by the DEA on Jan. 5—days before he would have been sworn into office and obtained immunity. Philippe had been wanted by the US since 2005 on charges of conspiracy to import cocaine and money laundering. He was popped by Haitian police and turned over to DEA agents immediately after appearing on a radio show in Port-au-Prince, and promptly flown to the Miami to stand trial. On Jan. 13, he pleaded not guilty to all charges in US Court for the Southern District of Florida, asserting both that the case against him is politically motivated and that he already has immunity as an elected official.

In his latest outrage, the Philippines' ultra-hardline President Rodrigo Duterte now threatened to actually impose martial law across the country if the drug problem becomes "very virulent." Reuters on Jan. 16 quoted him as saying: "If I wanted to, and it will deteriorate into something really very virulent, I will declare martial law. No one can stop me." In a comment apparently directed at the Supreme Court and Congress, he voiced open defiance of legal norms: "My country transcends everything else, even the limitations."

A New Year's Day prison riot in Brazil's Amazon riverport city of Manaus left up to 60 dead before aithorities re-established control the following morning—with many of the bodies decapitated, mutilated and burned. The uprising at the Anisio Jobim Penitentiary Complex (COMPAJ) is the bloodiest of several such episodes in recent years, pointing to extreme overcrowding in Brazil's prison system and effective control of many facilities by drug gangs. Authorities in Amazonas state say the COMPAJ rebellion was sparked by a fight between rival gangs. Local media reported that several of the dead had their decapitated bodies thrown over the prison wall. Twelve guards were taken hostage, and a still undetermined number of inmates escaped.

The case of 43 college students from the Mexican village of Ayotzinapa who disappeared in September 2014—and were allegedly murdered by a local narco-gang—continues to elicit outrage. Now, the parents of the missing students held a cross-country mobilization for justice in the case, arriving in Mexico City on Christmas Day. The "Caravan for Memory and Hope" departed from southern Guerrero state five days earlier. On Dec. 26, a special mass was held at the city's historic Basilica de Guadalupe in honor of the missing students, overseen by the Bishop of Saltillo, Raúl Vera, and the Archbishop of Morelia, Carlos Garfias—both well-known for their advocacy for Mexico's poor and oppressed.
