Hopefully, it might somehow get through to him.
If he is wrong, he should offer an apology.
Having been involved in come classified things, I was once asked to participate in a non-event.
Is it possible that Father Corapi might have referred in some way to some non-event that he was ordered not to disclose operational information about? Possible.
There could have been some operation regarding the Vietnam War in this regard.
For example, people who might have been involved in the failed rescue of POW's in North Vietnam might not have served in Vietnam except for that operation. Yet they could claim some sort of service in Vietnam -- especially landing in North Vietnam in the dead of night to free American hostages.
Things that are classified will not be released unless they have been de-classified. The fact that Father Corapi has friends in the Pentagon might mean he has done some classified work of some sort at one time.
It is speculated in The Miracle of Hiroshima that the eight Jesuits helped to provide information about Japanese operations in Hiroshima. And after the war, when they were exposed to lethal doses of radiation, and nothing happened to them, they may have been told by the US Government not to comment on that...
That would be an example of German citizens who are Catholic priests being asked to do something classified (not say anything) for the sake of the security of the United States...
Bttt
