You do get diced once in a while, but it is not necessarily game over G1 if sz2 or Égypt fails.
Germany can really be a tough nut to crack, and even if the German players dream of Africa and Moscow takes a serious blow on G1, he can really dig in and make it very difficult for the allies to get a foot in in Europe.
A chunk of armor in E. Europe, stacks of inf in western and Germany and an airforce threatening to take a shot at that essential transfer fleet can take a long time to crack.
When I feel I am behind, I often take more risks than usual - going for that 50% UK Navy battle, or making risky strafing attacks on an exposed USSR stack.
You can also try to advance faster with Japan - maybe try to take India J1 or by doing the risky pacific double move hitting both sz52 and the US battleship+transporter at the western us shore on J1.
