There is no such thing as "Internet routers"  there are my routers, your 
routers, and that guy over there's routers.  Even if you get your ISP to route 
it for you - that does not guarantee that any other network anywhere else on 
the internet will accept the route.  Getting your ISP to accept your prefix is 
arguably, only a small part of being reachable/routable.

I suppose that ARIN would say that they do not guarantee routability because 
they do not have operational control of Internet routers.
However, Wouldn't you say that there is a very real expectation that when you 
request address space through ARIN or RIPE that it would be routable?  I would 
think that what ARIN and RIPE are really saying is that they issue unique 
addresses and you need to get your service provider to route them. FWIW, the 
discussion of the military having addresses pulled back is pretty much a 
non-starter unless they want to give them back.  When the management of IP 
address space was moved from the US DoD, there were memorandums of 
understanding that the military controlled their assigned address space and 
nothing would change that.
I know this for a fact because I was around this discussion in the US Air Force.

Agreed - I called it out because ARIN, like RIPE, does not assert that the 
address blocks issued are "publicly routable address space" 
(i.e. which was Tim Franklin's original statement, but he did not have on hand 
the comparable ARIN reference for that point.)
