But I also sympathize with Bolivians in that they probably just want unfettered access to the sea without a different nation holding it over their heads. Every time a dispute comes up, i can see Chile being vindictive and blocking access.
Whatever. Plenty of countries don't have coastlines. They do just fine without throwing fits about their neighbors. Austria doesn't go around demanding that Italy or Croatia open their ports, even though Austria controlled ports now in Italy and Croatia more recently than Bolivia controlled ports now in Chile. This is just childish.
