There is talk that Canada should buy the U.S. Air Force A-10 Warthogs when we stop flying them in the next 2-3 years. As an article at the ironically named War Is Boring website says, the A-10 is probably not the right plane for Canada.
However, the A-10 might be an excellent fit for Mexico and/or Colombia. Armored, slow-flying but lethal ground attack aircraft are useful against drug labs and rebels on the ground.
One or more of the Central American nations might also have conditions for which they'd be appropriate. For that matter, so might the French engaged in anti-terrorist activities in Africa's Sahel. Any nation seriously engaged in anti-insurgency could learn to love the Warthog.
The Pentagon's choice to dump the A-10 signals more clearly than any words our military's fervent hope to never again engage insurgents. As though not having the tools would forestall the assignment ... pure madness, of course.
