Crimea is land-locked?? It’s an island and has a bridge on the eastern side connecting it to Russia. The straits there are just 3 km across I believe
OK so I was typing fast and the term land locked is not technically accurate - but you managed two mis-statements to my one lol.
It’s not an island but an peninsula and there is no bridge on the eastern side - http://rt.com/business/crimea-russia-kerch-bridge-857/ - they would like to build one precisely because one doesn’t exist.
The point is that overland access exists via the Ukraine
but not via Russia. Maybe this map will help you visualize http://www.map.hu/galeria/20090118195134.jpg
