Pan South American war in the early 20th century

Could an alliance system similar to Europe could develop in South America in the early 20th century and lead to war ?

What countries would ally with who

How would such a conflict be fought
 
yes

BUT there would have to be an aim

Secondary actors buy into the main aim to promote themselves

if the main aim was to bash Brazil, for example, British banks basically controlled Brazil by then
