South America is a big place, and there are a lot of countries. The situation isn't this simple. For example, Argentina is historically the most anti-US country of all South America, yet it's government and their supporters celebrated the US attack calling everyone who opposed it "communists" (all this while the government allows Chinese goods to be massively imported). Argentina's government will be trying to make a block of countries that are us-friendly (and be their leader of course).

Also, adding context, argentine elites are pro-us, but not as much as Brazil's elites and their supporters (who wear the US flag in protests)
