world war 2

can you give me a link to this? i can't find it on the web

 You won't find it. There were never any formal plans but Hitler and his cronies did fantasize about how Japan and Germany would divide the USA once the USSR had been defeated. 

 The diaries of those close to Hitler mention it.

apparently, brazil was the only country in latin america to send troops to europe

On the flags topic...

The states of the US are essentially provinces, while the countries of Great Britain are essentially colonies. The process of giving them sports team started whn the Brits wanted to play international football, but couldn't find anyone to play with. So they gave Scotand and Wales their own football team. This eventually spread out into other sports. Their flags are also important in the Commonwealth Games where it must have been very dull seeing the Union Jack win everything.

That doesn't mean Brazil was anti-Fascist. In fact, the existing government in Brazil at the time was Fascist and they had flourishing trade with the Nazis. When war broke out, they tried to posture themselves in an ambiguous way, pitting both sides against each other, trying to get the best deal. Uncle Sam made trading with Germany impossible, and launched a diplomatic offensive, and won through in the end.

Brazil was under the dictatorship of Getúlio Vargas and maintained its neutrality until the beginning of 1942. After several German submarine attacks against Brazilian ships between February and August that year in the Atlantic Ocean Brazil sided with the Allies declaring war against Germany and Italy on August, 22 1942. Brazilian naval forces helped to patrol the South and Central Atlantic combating the German's U-boats. Brazil hosted, in the Northeast of the country, at Natal, the largest United States air base outside its own territory, and, at Recife, the U.S. Fourth Fleet. This air base gave support to the North Africa campaign. In 1944 Brazil sent the 25,000-soldier Brazilian Expeditionary Force (FEB) to fight in Europe, the only Latin American nation to send troops to Europe. This force joined the U.S. Fifth Army under General Mark Wayne Clark's command and participated in the Italian campaign until the end of war. Brazil sent two Air Force Groups, one of them a Fighter Group (the 1º GAVCA, or 1st Air Group, nicknamed 'Senta a Pua', which means 'Feel the Spur'), also based in Italy.

this is what i found on wikipedia "participants in world war 2" under brazil.

^Yep.

 Hence, how so many countries "participated" in WW2.

Belize was not an independent nation until the 1980's.  During WW II it was a British colony, known as British Honduras.

Got it.

Which world war do you think has had the most effect on current affairs? (I hope I asked this question correctly and hopefully i'm not breaking the rules of what to talk about here)
