It depends on your goal. If you want to build the bomb and survive in the long run, it will be difficult. If you just want to make a big bang with no other requirements, unfortunately it's pretty easy to do.

We could be happy about the two things that it is not that easy to get enough plutonium in the required purity and that most people love their lives.

Is it possible that most terrorist groups understand the cost/benefit trade off? In other words, if you have folks capable of designing and/or assembling a nuclear device, those aren’t people you just throw away.

I understand that terrorists don’t value lives highly, but you don’t see experienced bombmakers actually conducting suicide attacks for a reason. They’re valuable alive.
