Dear Editor:

We should write to President Biden that if he is to secure a nuclear pact with Iran or North Korea, he must not repeat the fatal flaw 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.
