Its an ill-wind that blows no good to a military profiteer somewhere.

The LA Times has a fairly in-depth report on the migration of the Mexican Zetas into Guatemala.

But I found this Reuters piece about Brazil gallantly loaning Guatemala the money to buy some Brazilian anti-drug planes:

Brazil will finance Guatemala's purchase of six military airplanes and a radar system to help it tackle a growing threat from drug gangs within its borders, Guatemalan President Alvaro Colom said on Tuesday.

Brazil's state-run export bank BNDES will fund the $99 million purchase with a 12-year loan, Colom told reporters in the Guatemalan capital during a visit by Brazilian President Luiz Inacio Lula da Silva.

The Super Tucano aircraft, made by Brazil's Embraer (EMBR3.SA) (ERJ.N), are due to be delivered within 18 months.

The turboprop airplane can be used in a variety of roles ranging from pilot training and airborne surveillance to ground attack, according to the Embraer website.

"The most important thing is that we'll have the same system as Colombia and Mexico so we can better coordinate the security of our borders," Colom told reporters.

More from the LA Times about the quandry Guatemala is in:

Guatemalan police commanders say their 20,000 officers cannot match the firepower of the Mexican traffickers, who have made growing use in Mexico of military-type arms, such as 40-millimeter grenades and .50-caliber rifles capable of piercing armor.

Recent seizures in Guatemala have yielded similar weapons. "These are things we have seen only in photos of Iraq and the Gulf," said Larios, the police commander. "Not in Guatemala."

But devising a response is complicated by Guatemala's troubled past. The memory of the army's brutal conduct during the civil war means that it would be politically dicey for Guatemalan leaders to respond by mobilizing the military, as Calderon has done in Mexico.
