We should sell NEW American hardware to Mexico, Peru, Columbia with a trade in for all their Russian hardware which we could overhaul and give to the Afghanis a lot cheaper than building Brand New equipment as with the AIRINC / CNTPO deal. That would effectively kick Russia out of all Latin America but Venezuela and Cuba.
