Germany, Berlin 1936, World decided to pick the jew side years later.
Mexico 1968, entire world had commie student rebellions but Mexico had one that busted the alliance between government and universities which meant opposing interests (government undermined the sectors which some opposing universities were filling with professionals), also bad rep because they shot people, tank rolled over the bodies and raped them after.
West Germany, Munich 1972 had the jew incident that made them have bad rep (again).
Leafland, Montreal 1976 started the global leaf thing and was a couple of years prior to Canada getting mega cucked into the 80's to the form we know today.
Soviet Union, Moscow 1980 was boycotted by seething mutts and some protests here gave place to early ideas towards Perestroika.
Muttlandia, L.A. 1984 also got boycotted by seething commies and the event made tons of minorities relocate there, the Reagan Recession already slowed down the city and towards the late 80's it had lost its place to Miami.
South Korea 1988 was the same year when they started the jewdification of the country to what we know today, transitioning from military junta to corporativism with the triads taking big power, the first big year as they say.
I don't recall the effects of Spain, Barcelona 1992.
Muttlandia, Atlanta 1996 made the city bankrupt and niggers ran amok even more soon after, destroying the city's important place in the East Coast as the adult fun place (casinos, hotels with "executive room service").
Australia, Sydney 2000 got lebbed and chinked hard after that, also The Great Canberra Fire.
Greece, Athens 2004 got massive amounts of denbts because they are lazy fuckers who had previous ones and decided to get more loans to build places now in disuse, had to sell their butthole to the GGermans.
Chink, Beiching 2008 was indeed a good sign to the chinese hegemony plan but was also the Great Recession that fucked their population control although did get them big trade deals which also started their housing bubble which is yet to explode.
Bongland, LONDON 2012 i also don't recall that much because brits have been fucked since a long time ago, since 2014 they started getting even more fucked but that was a global thing with the digital new era.
BR, Rio de Janeiro 2016 fucked their ass in denbts (along with World Cup), infrastructure collapses and ended with a political crisis with the commie jew presidents Dilma and Lula.
Olympics are used for political trickery which include fucking someone over with seemingly-benevolent loans, planned incidents and/or landmark beginnings for "opening to the world".
