None of those factors remotely forced germany to do anything. They had the enlarging fleet. They had increased trade. They had the huge land army. Their ally declared war on a weak country, but Austria-Hungary didnt HAVE to do even that. When they did, though, they knew their action would trigger mutual defense pacts.
Bluntly, they did it anyway because they wanted to have a war.
Germany did not have to set foot in the neutral territory of Belgium. Germany did not have to attack France. They did it because they wanted to, and because they thought they would Win -- and thereby be treated as a superpower.
It's obvious that Germany's ambitions made england uncomfortable, and its obvious there was an arms race. And your citing of the nuclear arms race MAKES my point for me (thanks by the way)...the nuclear arms race was even more intense and prolonged, but there was no nuclear war. In the same way, there didnt have to be a World War as the last century ioened. Austria-Hungary and Germany chose to make one.
There's just no way to say that the war was England's fault -- at least no way that's rational. England chose political/economic methods; Germany invaded France.
