If the US was able to put men on the moon in the '60s with less computing power than a modern cell phone, why is it that modern countries such as China or even North Korea can't pull it off?

For one thing there's no good reason to do it, so you have to be willing to spend hundreds of billions of dollars just for the fun of it.

For another, there's a lot more to it than just shooting a rocket at the Moon. You have to develop space suits, docking mechanisms and procedures, landing spacecraft, re-entry methods, rockets that can launch at least 50 tons to translunar injection, etc.

Finally, China is working on completing a manned Moon mission by 2025, so these days they _do_ have the cash to do it just for the fun of it.
