Is there no-one who can be trusted over Afghanistan?
Afghanistan and trust are going to be our focus on World Have Your Say.
Nato is now restricting operations with Afghan troops after various attacks from within their ranks.
It again raises the issue of how to build trust between foreign troops, Afghan troops and Afghans themselves.
Not to mention, the harder job still of finding some trust on which to build a dialogue with the Taliban.
We have guests who will try and help us see the way ahead.
