No, the public should not have the right to know this. There should be a limit to what is made public when making the plans public might endanger national security. For example, think about what would have happened if the US had publicized that we were planning the D-Day invasion. If we had made public the date on which it would happen and (most importantly) where it would happen it would have been horrible. Equally, we should not be letting other countries know what our diplomatic bargaining positions are. We cannot let them know what we are planning to try to get from them or how much we are willing to give up. This, too, would endanger our security.
