You’ve got to have principles. As many as possible. For all eventualities. Take former German chancellor Gazprom Gerhard Schroeder (SPD), for instance. Please.

His nomination to the board of Rosneft, Russia’s largest oil company – majority-owned by the Russian government – is breathtaking in its brazenness. You can’t really call it a sell-out, however. This guy sold out long ago.
Rosneft is under Western sanctions over Moscow’s role in the Ukraine crisis. By pure coincidence, Schroeder, who calls Vladimir Putin his friend, has regularly criticized any moves to impose sanctions on Russia.
I know it’s hard to take an unpopular stand sometimes, especially when it is unethical, mercenary and just plain wrong, but he certainly is consistent here, at least.
“Schröder macht sich zum russischen Söldner.”
PS: Germany is predictably outraged about this (not) (or not particularly). But rest assured that if this had been a US-Amerkan oil company there would have been hell to pay.
