It appears that the Russian and US military are talking. Perhaps like the North Koreans, they do not want to call Trump's bluff.
Meanwhile the Telegraph posts
Boris Johnson has said the the Kremlin “must give answers” after an international watchdog confirmed that Sergei Skripal and his daughter Yulia were poisoned with a "high purity" strain of Novichok nerve agent in Salisbury.
The Organisation for the Prohibition of Chemical Weapons said that it had been able to “confirm” the findings of British scientists about the nerve agent.
It represents a significant boost to Theresa May, who has said that Russia was directly responsible for the attack. Mr Johnson said that only Russia has the “means, motive and record” to have carried out the attack.
