The one Gbyte thumb-drive effectively defeats many of the advantages of a separate classified computer network. A possible solution is to encrypt all traffic on the classified network and data stored on hard disks. However a spy can still up-load almost everything on a single thumb-drive if he has authorized access to the data. It’s my understanding that the Chinese fully compromised Los Alamos National Lab and got everything (correct me if I’m wrong about this). Supposably the Chinese know everything concerning US nuclear weapons technology.

I’m morally confused about the death penalty (I don’t like giving the government that much power). However there probably should be a warning written on the cover of every highly classified document that says:

“You will be put to death if you reveal this information to any unauthorized person!”

Then actually carry out this threat everytime a spy is caught (no exceptions, no plea bargains).
