Maus = Badass
Me262 = Badass
Lol.
1942
Porsche: "How much steal is avalable?"
Hitler: "Apparently, enough to put arms into production but not enough to expend"
Porsche: "Ok, well give a load to me and hope that my one tank wins the war"
Hitler: "Awesome"
1944
Porsche: "Now, how about the spare parts and fuel supply?"
Hitler: ....
The Maus was a shit tank, in the same way the Desert Eagle is a shit pistol. E.g: Tempest > Maus.
The Me262 was shit, it was a major supply nightmare, four engines to keep each 262 flying for a week wile running extremely low on the rare materials needed is not "badass", its wtfpwnting yourself in the face!
On the original point, yes the Italians needed constant German intervention, yes the British pwnt them in the Balkans and North Africa (Both making Germany step in when, especially in the case of north Africa, the German army was stretched thin.) The British Swordfish Taranto Raid that Deranged mentioned is perhaps one of the most amazing successes of entire war and locked the Italian fleet out of many actions it could have been committed to.
