What is common in the United States, is rather rare in Germany: Expressing support of our soldiers in Afghanistan.
While most US critics of the wars in Iraq and Afghanistan make extra efforts to distinguish between criticism of the strategy/purpose of the wars and the service of the troops, such differentiation usually is not made in Germany. I have never seen a car with the bumper sticker "Support our Troops."
The Bundeswehr troops do not get much support from citizens, media, celebrities or politicians. Instead many soldiers are concerned about the opinion polls that indicate popular disapproval of the Afghanistan war.
Therefore the Atlantische Initiative (my day job) has teamed up with Germany's biggest daily newspaper and started the campaign "Feldpost für unsere Soldaten!"
We encourage our readers and members to write short personal messages of support for the Bundeswehr troops. We will then forward the best ones to the various bases in Afghanistan. Several hundred messages have already been published by our partners at the tabloid Bild (in German).
In other words: We try to apply a US concept (Supporting the troops, even if you disagree with the war) in Germany. Hopefully it will help the NATO mission in Afghanistan and promote the transatlantic relationship in general.
