Andrew Whelan at the AP has a very interesting article about the cocaine boom in Peru and its relationship to the revitalized Shining Path. One question is whether the current version of SP bears any resemblance to the 1980s, and the answer seems to be no. Under Abimael Guzmán, it had a fanatical, utterly insane, but ultimately clearly articulated ideology that mostly involved trying to kill everyone. Nowaways the SP eschews killing civilians, and focuses primarily on drug trafficking while sprinkling in some lectures to peasants about how the government does nothing for the rural poor (which they have long known).
But even Peruvian government officials openly say that the SP is thriving because Lima doesn't care about what happens in rural areas. Most peasants don't care about ideology, but SP helps them set up a coca farm, which generates far more income than anything else.
The military alone can't defeat the insurgents, say officials in the region. They say the bureaucracy that has hindered development must be surmounted.
That nicely sums up one of the problems with the "drug war" across Latin America.
