Netherlands is a small peaceable country. There is nothing they can say, nothing they can do, except demonstrate the civilised dignity that is in short supply in other countries. Many leaders have taken the opportunity to stand in the spotlight and do their John Wayne act. Using a tragedy to boost your public image is not showing respect for the dead. Shouting macho words at Mr Putin will do what? Make him scared? He isn't scared of words, all they do is make him even less cooperative. Mark Rutte's restraint requires more balls to pull off than the oven-ready outrage that would placate his critics.
To get through Puties thick skin will require diplomacy that exploits his vanity and his self image as a leader of historic greatness. I'm talking about guile not appeasement.
There is nothing they can do? There is nothing the EU can do?
Your citizens have been slaughtered. Their bodies dragged through the fields. Balls? The EU is a great power. But a power without balls.
You like Putin fucking you up the ass? Enjoy your fucking.
