We have heard a good deal. recently. about the possibility of a real outbreak. the possibility of real fighting. For instance. the following headline appears in the Washington Daily News of today: "Convoys of GIs Defy Red Threat. Allies Urge Russians To Join Talks on Crisis in Berlin." On page 3 is another headline which reads: "Reds Kill Refugee After He Goes Over Wall." to get on our side. They are closer to a shooting war every day at the Berlin wall. They are shooting water cannons. they are lobbing grenades. over the wall. the East Germans and the West Germans have been shooting.
