Novichok’s gas acts immediately. To allow Scripal and his daughter to live, they must be given an antidote within 15 to 30 seconds after the attack. Russian authorities denied that Novichok would ever been developed in Soviet Union. In addition, Novichok was destroyed under the supervision and control of US experts during the time USSR existed. This means that the attack could not have been carried out by anyone other than the West, who had Novichok and an antidote ready.
It doesn’t feel like a war, it feels like a crusade against Russia.

In its statement, the European Union expressed shock at the offensive use of any military-grade nerve agent, of a type developed by Russia, for the first time on European soil in over 70 years. http://www.consilium.europa.eu/en/press/press-releases/2018/03/19/statement-by-the-foreign-affairs-council-on-the-salisbury-attack/
