"We've heard that one before." 

Who, out of a folk consisting of whiners and pacifists, should attack anyone today? A country which isn't even able to fight in Afghanistan's south because it's frightend of dead soldiers? Doesn't look to me like Germany will attack anybody in the next decades. 

And surely there won't be any German tanks attacking another country, in order to get money back or for any other reason.

We've heard that one before.  

 "Germans will be Germans" 

If you look at the facts, this isn't true when it comes to National-Socialism.

But it is true, that in Germany you have different minority-groups which are seen as "evil" by the mainstream public. In the years before and during the National-Socialistic Regime it were the Jews (which were often rich).
Today the new "evil" group in Germany are just the rich, no matter of what religion.

So if it goes against "the rich" or the "managers", in Germany you have not only the mainstream public behind you, but also the Media, which are mainly controlled by socialistic journalists.
So it's right to say Germans will be Germans when it comes to envying other people's wealth.

But at least it's not as bad, as it was 70 years ago. Yet. This time even the average German started to think about the Government paying criminal people to get information. And some even understand "the rich", who put their money to a foreign country, because the last Socialistic/Green Government cancelled the "Bankgeheimnis" (Bank Privacy Law) in Germany, so that Tax-People know everything about your financial situation. This part is even not liked by the average German.

However there is still an accountable number of Germans, who don't think that  breaking another country's law is the right way to go. And surely there won't be any German tanks attacking another country, in order to get money back or for any other reason.

Germans will be Germans.
