“Yugoslavia was created by force by uniting many different nations under one government by Tito” No, Yugoslavia was created after the 1st World War after the dismantling of the Austro-Hungarians Empire. It was the Kingdom of the Croats Serbs and Slovene and was a creation of mostly intellectuals who thought that populations speaking the same language could share the same State. It was created around the only independent State before WW1 Serbia (which took it from the Ottoman Empire) and the King, Peter Karadjordevic 1st of Serbia. It became the Kingdom of Yugoslavia (Jugo Slavija, meaning the Slavs of the South) under Alexander, his son and heir. Tito just took power after WW2 and created a Federation of Yugoslavia which is not ending to die.
“Look what happened when the central government couldnt force the Nations to be in the Federal state anymore. Also the Majority of problems in Africa like Ruanda or currently Sudan comes from the fact that during Imperialism the European Monarchies draw imaginatory state lines that cutted the ethnical populations to many different states and that made the states very unstable,becouse the continuos conflict between different ethnic groups”:
Sorry but wrong again. The states composing the U.S.A also have strait borders and that isn’t a problem. Same observation can be made with the international border between U.S.A and Canada.
Which Ethnical populations: They are nomads, and to draw a straight line in a desert isn’t by itself a bad idea.
The problem came because the populations moved and well, ignore the borders…
This could have renegotiated before the Independence or after, but all the new states accepted the Colonial inherited borders. Only Morocco and Algeria negotiate their borders, and never succeeded to really resolve the problem of the Polisario, for example, and that without intervention of the bad Imperialists.
