I had not heard of this EU diplomatic stand until now, but it sounds like it was a good idea. I expect it caused awkwardness, though, for the diplomatic staff mounting the protests, by inviting dissidents to embassy functions, which may be why the policy seems to have been dropped. However, I am glad that both the Czech Republic and the Netherlands are remaining firm; it is specially notable that the Czech Republic, formerly under a socialists tyranny itself, is one of the countries not to flinch in the face of Cuban pressure. I think that should tell those other EU countries, such as the UK, France, Italy and Germany, etc, something. No?
It is a mistake to appease tyranny. I am disappointed that this 'lesson from history' has been forgotten so quickly.
