I use a bred knife to slice cheese off a block every day. Line it up and push down, one hand on handel the other on the spine at the top. It works better than any other knife to slice cheese blocks.
This post makes it sounds like I am committing a war crime.
The point of the film is to show how horrible war is in a context Americans can relate to. If they made a more realistic alliance, down some sort of real life right / left politics the message would be lost and it would be held up as some sort of propaganda film by one side of politics with the other side using it to justify why they're correct.
So, yes the "alliance between the California and Texas" is a very deliberate choice.
