Afghanistan. Mostly dry mountains, not enough arable land, and the mountainous terrain make it hard to build roads, etc. Also landlocked. I simply can't imagine the country being anything but an utter train wreck for a considerable while.
Are some countries just doomed to poverty and unrest, simply due to the fact that the landmass of said country is so unsuited for economic growth?
For instance we say countries like Korea, Japan developed despite not having much resources but Korea has significant coal, tungsten deposits, Japan produces stuff like iodine and both countries the hot rainy summer climate makes it ideal for rice farming. It's a far cry from regions like Afghanistan.
