They failed as it's still leaning. They need to try again and make it actually straight this time. It could be interesting to try and also straighten the upper portions too since it wasn't built totally straight.
That action wouldn't be well received in Italy in real life. We have a zillion of straight towers but everybody talks about and goes to see the odd leaning one.
Superman eventually restored the original leaning angle.
