According to https://www.worldometers.info/coronavirus/, Singapore has a total of 31 coronavirus deaths, one of the lowest per capita death rates in the world. So it seems to have worked very well.
That's great, so the most important data point was missing from the article: that it was worth it, as lots of lives were saved. It's just the opposite of the 2nd world war tracking where it caused deaths.
