Sohail Assad with leaders of ASPRET
Given the involvement of Vargas, the occasional visits from Assad, the use of the organization for Shia missionary work, and the staff members who are likely converts to Islam, it seems reasonable to suspect that ASPRET is funded at least in part by Iran, with the money flowing through Assad to Vargas. ASPRET may be a more or less genuine organization seeking to defend the rights of the Quechua, but that's not all it is.

And this brings us to Sacha. Who is Sacha? He's the guy to the right of the general:

Sacha served in the Peruvian army...
...and he identifies closely with the "Movimiento Etnocacerista." The Etnocaceristas led military revolts against previous Peruvian governments. Antauro Humala is currently serving a 25 year prison sentence on account of such activity, while his brother Ollanta is the current President of Peru. ASPRET was heavily involved in supporting Ollanta's presidential campaign:
