No, there aren't any surprises in that Chewbacca. I find it good to see at least one politician, Corbyn in this instance, not talking a lot of BS. Don't you think we will have to do business with Russia Chewbacca or would you like - well what exactly would you like them to do.
Nothing is likely to happen, if the government has a sane head when dealing with this, until the OPCW analyses their samples. We need the rest of the world backing us on this. There are still questions to be answered. Radio 4 broadcasted an really interesting interview yesterday while they were trying to find out if reports that Porton Down scientists are not able to identify the nerve agent as being of Russian manufacture, and have been resentful of the pressure being placed on them to do so. Porton Down would only sign up to the formulation of "a type developed by Russia" after a difficult meeting where this was agreed as a compromise formulation
The interview was with a risk consultant who had been an inspector for the Organisation for the Prohibition of Chemical Weapons.
... they'll be able to produce and characterise the sample and then come back. It's really a question then as to whether that characterisation is sufficient to support the UK's assertion or it's slightly more generic term of just saying a nerve agent that appears to be of the characteristics of Novichok.
The tension they you mentioned between Porton and the Government is entirely credible; I don't know whether it's true or not, but it's entirely credible where scientists are always looking to ensure that degree of accuracy whereas politicians do thrive a little more on ambiguity.
This is really not about whether belittling the leader of the opposition is clever - it rarely is and, as these things do, usually tell us more about the belittler than the belitted. It's about whether you want another war or, at the least, a cold war. That certainly would not be clever.
