South Korea and Taiwan were definitely not first world countries when they started. Not even inhabited by white people (so less likely to be favored by 60s America, for example).

The Persian Gulf states (Saudi Arabia, Qatar, UAE).

Israel also wasn't developed in 1947.

Let's not ignore facts when they're inconvenient.

In the Western Hemisphere the US track record has been a total mess but in the Eastern Hemisphere I'd say about 30% of the time US allies tripped on their own feet on the way to prosperity.
