It's not about whether countries have a conscience. Countries are not persons. It all depends on what type of goods the trade with certain countries is focussed on, in what way these goods are affected by the sanctions and what type of wiggle room individual companies in these countries have and what risk they are willing to take. And here the ownership structure of the companies plays a role, too.

In general one should not read too much into such a diagram. There is a real problem only if the sanctions are circumvented. And, of course, maybe it shows that we should extend the sanctions to other type of goods.
