Really? All of them? Are you sure about that?

I believe there is a policy proposal in the ARIN region which, I have it on 
good authority
is still active.

True, it doesn't technically designate more RFC-1918, but, it does create a /10 
of space
for shared use for the purpose of LSN intermediate space or other carrier-level 
private
network usage.

More likely they are making the assumption that their private internal use of 
the address
space won't conflict with DoD's (apparently) private internal use of the 
address space.
