The problem is exactly due to the things you mention, "intervening in Africa and South America whether for business or political reasons". Yes, they did that, to promote dictatorships in our continent. Excuse us if we hold a grudge against the US, they're in part responsible for the situation that we're in now (of course, we're still the biggest responsibles)
I'd prefer that the US doesn't meddle in the politics of other countries, they proved in the 70s and 80s how much harm they can do. And I'll never forgive them for that. So yes, a very negative perception, at least from my part
