Operation Valkyrie - A Three Hour Delay

There's a three hour delay between the bomb going off and the implementation of Operation Valkyrie. So when Tom Cruise lands, he's like, dude, are you kidding me? It was three hours ago. The second problem was that they didn't cut the lines from the Wolf Slayer. And apparently even Goebbels mocked them later after this. They ceased communications. All they could do is kind of clumsily mess up the communications to delay it. Instead, Germany had a lot of conflicting reports and different things going on. "It's Hitler alive. It's Hitler dead. Well, who's in charge?"
