LETTER: Nuclear deal

To the editor:

In the case of President Biden securing a nuclear agreement with Iran or North Korea, he should not repeat the mistake of the first Iran deal. It imposed a waiting period for the inspection of suspected sites. This would have allowed them  to move the materials for making a nuclear weapon, such as enriched uranium, to a second site during the waiting period for the first site, then when the second site comes under suspicion, it will have a waiting period during which the material can be moved to a third site, and so on.
