Well... that is what I thought too. It looks calm in Chile. But I digged it a little, and , surprise, surprise, there is a lot of bad blood between Chile and Bolivia. Actually Chile “stole” Bolivia’s access to the Pacific after the so-called Pacific War of 1884. Bolivians never forgave ! It is pretty much like a non-stop cold war between the two countries. So, you see, Chile isn’t taking any chances.
That type of problem exist between Chile-Argentina too ,they are on the verge of war 4/5 times in last century alone , somehow averted those wars. They fuckedup their borders in patagonia and Andez and still occasionally suffer panic.
fact is Bolivia and Argentina is nowhere near Chiles economic and military might , and even now Chile have 60+ F-16 , atleast 20 are Block52+ . Not only fighters ,but CAS , refueler aircraft everything . They are more than sufficient .probably strongest military in southern hemisphere. I bet they are probably better than Ausis without F-35.
It's actually constitutional there that govt need to spent a % of total copper export in defense , probably Pinochet era rule ,no democratic govt want to piss military so the continue to spent like this....but even then they vulture defense products , like former german leopard , former dutch F-16 and if rumors are true then this .
Poor Bolivia have no chance anyway to get those land ,they are the one who start the pecific war though , so it's Karma..
