“Even President Reagan couldn’t understand him. During an early briefing Casey delivered to the national security cabinet, Reagan slipped Vice President Bush a note: “Did you understand a word he said?” Reagan later told William F. Buckley, “My problem with Bill was that I didn’t understand him at meetings. Now, you can ask a person to repeat himself once. You can ask him twice. But you can’t ask him a third time. You start to sound rude. So I’d just nod my head, but I didn’t know what he was actually saying.”Such was the dialogue for six years between the president and his intelligence chief in a nuclear-armed nation running secret wars on four continents.”
