Well, the Czechs have signed a deal with the US to install an ABM radar which is clearly directed at least as much at the Russia as at Iran, and they are shocked to discover that there are problems with oil deliveries:

Shipments to Czech oil refineries through the Druzhba pipeline, which ties Siberian fields to the Czech Republic, are declining, the Czech Ministry of Industry and Trade said. It did not say by how much.

You sign off on a policy that is pretty explicitly threaten Russia, and you are surprised when they retaliate?

What planet are you on?
