You consider Tibet to be a western country? Yeah ok...
Tibet's government was founded when the Communists invaded. You know, the normal way, with soldiers and guns. And you may be aware, that a war usually involves violence and blood. Oh and then there was a violent revolution against the rule, during which 100,000 people died while the modern government of Tibet crushed them into the ground. And then they instituted PRC policies resulting into up to a million deaths during their collectivization process. Boy, id hate to see what you consider an actual bloody foundation.
Iceland was a colony of Denmark, and achieved independence after Denmark was invaded by Nazi Germany in a little not at all bloody event called World War 2.
The government of Norway was overthrown during WW2 as well. Oh and then the newly formed post war government, violated the Geneva convention and forced German POWs to run through minefields in order to clear them out. Stay classy Norway, stay classy.
Slovenia achieved its independence during the Slovenian Independence War; where they rebelled against the Yugoslavian government. The Yugoslavians leaflet bombed them with messages threatening to 'crush all resistance.' When the Slovenians didn't back down, the Yugoslavians rolled in tanks.
Pictured: The Yugoslavian plan put into operation to presumably hug the Slovenians and congratulate them on their 'totally not a violent war,' independence.
And the Czechs and the Slovakians... we'll they were just that freaking awesome. And they should have just kept going on Prague Spring and taken their independence in the 60s.
