This causes an infinite loop. \cite gets unpacked into something
involving \cite, which gets unpacked into something else involving
\cite, etc. Not so good. The problem is that LaTeX does not expand
\cite when you give this command, but only when \cite itself is
expanded. That is: \cite, even though it is a command, works like a
variable. Consider:
\newcommand\mystuff{a}
\newcommand\inparens{(\mystuff)}
\inparens
\renewcommand\mystuff{b}
\inparens
This will print "(a)" then "(b)". This is actually quite useful
sometimes, and could equally well be done with more complicated
commands. (This kind of thing is done in the LaTeX core all the time.)
The standard way around this kind of thing is:
\let\oldcite=\cite
and then you redefine \cite in terms of \oldcite. The point is that
\let actually assigns the *expanded* form (at that point) of \cite to
\oldcite, rather than making \oldcite an alias for \cite (which would
just give us the other problem back again). So, e.g.:
\let\stuff=\mystuff
\renewcommand\mystuff{c}
\stuff
will still print "b", not "c".

I am not sure if i adapted your idea correctly. If i set in the
preamble the following code
\newcommand\newcite{\texorpdfstring{\cite%}{}}
\let\cite=\newcite
Latex stops with the following error:
Runaway argument?
{\texorpdfstring {\cite \let \cite =\newcite \par \renewcommand
{\bibsection \E
TC.
Other way around:
\let\oldcite=\cite
\renewcommand\cite{\texorpdfstring{\oldcite...whatever...
