Did Dell instruct Bühler?

Looking at the Wikileaks cables from Belgrade and Pristina I noticed one cable from ambassador Dell from januari 2010 in which he utters claims on Northern Kosovo that seem rather closely related to what Bühler more recently has stated.

Some quotes:
¶2. (C) Currently, we have a growing, if still somewhat
fragile, consensus within the international community in
Pristina that the time is right to end the years of drift on
the north and to alter the dynamic of a hardening partition
between the north and the rest of Kosovo. In part, this is
sparked by the new willingness among Kosovo Serbs to engage
with Kosovo institutions. It also stems from Belgrade's
increasingly aggressive actions in the north (e.g., seizure
of the Valac electrical substation; unilateral appointment of
Serb judges to illegal parallel courts) that have underscored
to representatives of the international community on the
ground the risks of continuing to do nothing. For ten years,
we told the Kosovars to trust us -- "let us handle the
situation, and we will protect you" -- and now the government
of independent Kosovo is increasingly asking us when we are
going to make good on that commitment. KFOR is drawing down
(in six months NATO could take a decision to cut its forces
in half). We need to take advantage of a unique opportunity
that has crystallized and act now while we still have a KFOR
presence capable of handling any contingency.
[..]
We know, however, that there will be difficult
challenges that pose risks. For example, EULEX must get
serious about rolling up organized crime networks in the
north that feed the parallel structures and make the current
situation unsustainable. The northern Serbs are the first
victims of these thugs, and there is a growing body of
reports that they would welcome a change if EULEX can deliver
it. We must, also, deal with the blatant theft of Kosovo
property that has allowed Serbia to, in effect, seize the
northern power grid in Kosovo. Dealing with these issues
will require hard choices and fortitude.
[..]
In recent meetings with Boris Tadic, both Angela Merkel and Nicolas
Sarkozy reportedly emphasized that Serbia's path to Brussels
runs, in part, through constructive relations with Pristina.
This is the perfect message. Brussels needs to repeat it --
regularly.


It looks like Bühler has heard he same story. However - as the pressure on the Northern Serbs with border blockades shows - Bühler and Dell in the end don't believe their own story.
