As already said: NATO enlargement.
Okay...you mentioned Georgia and Ukraine...
Well, Georgia declassified itself quite thoroughly during the last escapade.
And in Ukraine the polls show that a majority is AGAINST a membership in the Nato.
In what way is that Germany's fault???

According to numerous independent polls conducted since 2002, Ukrainian public opinion on NATO membership is split, with the majority of those polled against joining the military alliance and many identifying it as a threat.
[37][38] According to the FOM-Ukraine pollster, as of April 2009, 57% of Ukrainians polled were against joining the alliance, while 21% were in favor.[39] A Gallup poll conducted in October 2008 showed that 45% associated NATO as a threat to their country, while only 15% associated it with protection.[40]
Who do you think should force them into the NATO? And why???
Influential Ukrainian politicians like Yuriy Yekhanurov and Yulia Tymoshenko have stated Ukraine will not join NATO as long as the public continues opposing the move.[41]
Germany's fault???
The same country which decided to get rid of atom on its own soil within two decades and today is very nervous about planned construction of French atom plant in Western Poland.
Well, the new government in Berlin just decided to go awhile longer with the atom plants...

BERLIN -- The victory of Chancellor Angela Merkel's new alliance in elections last month promises to extend the country's use of nuclear power -- and reignite protests among those who have fought to phase it out.
Russia is going to construct a nuclear power plant in Kaliningrad.
And now guess:
who's gonna be the EU partner for the project ?
I think here you have the why:

The pair of reactors will secure a continuous supply of power to Kaliningrad with excess power being exported into the EU market. Lithuania, Poland and Germany are potential customers.[4]
