Flip through this link & you'll see Baku changed hands a few times. Brits, Turks, ( almost ), & Russians. Not exactly an unconquerable locale. http://ourworld.compuserve.com/homepages/usazerb/246.htm as well as the agreement on the Baku-Batumi pipeline on the usage of Azerbaijani and Transcaucasian railroads created a legal basis for Turkey to get the use of Baku oil. Transcaucasian railroads, did we get that? & that was WW1. & here is map of Georgia. Germans may send northern pincer through there. Terrrain not too rough. & below is the status of roads/rails circa 1926-1940. http://www.thewineman.com/geo_map.htm In 1926 Georgia had reached its prewar level of industrial production; transportation was restored; area under cultivation exceeded its pre-war level and cultural construction expanded as well. As a result of socialist construction and the successful completion of the first five year plans, Georgia had transformed itself into an industrial-agrarian country with a diversified, collectivized agricultural system. In 1937, industry's share in Georgian economy was 75.2% and 800 new industrial installations were constructed. The industrial enterprises built or totally reconstructed under Soviet power reportedly accounted for more than 80% of Georgia's industrial productivity. More than 8,000 km of highways and 250 km of raillines were built. By 1940, Georgia's Gross Industrial Product had increased by a factor of 10,2 over its 1913 level. 8000 km of highways, & 250 km of railines. A bit different than Libya eh?
