The US still fields missiles with "1960s tech":

I'm not so quick to dismiss these Iranian missiles. They seem to be accurate and able to effectively perform the job they were meant to do. It's a mistake to classify military technology as lower=worse/higher=better like it's a tech tree from a videogame. Inertial navigation systems like these missiles seem to have are actually superior to GPS in many circumstances that are relevant here. Yes, they drift, but that's not a huge issue over a short flight time. More importantly, they're self-contained, jam-proof, and don't rely on a service provided by an adversary.
Those missiles landed dead-center on buildings. (Seriously, look at the images!) This demonstrates an impressive operational capability to select which targets to destroy.
