You seem to be working under the assumptions that A) German foreign policy changed significantly after 1912, and B) that such a change was made in an attempt to compensate for domestic crisis.

However, there were no such incidents domestically. The only one that even comes to mind is the Zabern affair in 1913, but which had no impact on foreign policy and in some opinions shows the growing strength of the German parliamentary system relative to the aristocratic (though the military and aristocracy largely emerged without tangible punishment).

Germany had a thriving economy, a robust elected government, perhaps the strongest organized labor movement in Europe, the most progressive social programs in Europe, and a vibrant academia considered the best in the world (arguable subjective opinion, of course).

Further, I can't identify any particular change in foreign policy during the period highlighted, except perhaps for the de-escalation of the naval race with Britain where Germany reached agreement with Britain and stepped down its efforts to overtake the Royal Navy.
