Yes, U-233 is about as helpful in making a nuclear bomb as U-239, in other
words not much.  U-239 has a half life of only 23 minutes so your strategic
stockpile of U-239 bombs isn't going to be good for very long. The two
isotopes are similar in another way too, they both produce so many gamma
rays even a suicidal terrorist in a led suit would be dead before he was
half finished making the bomb.
