1 big thing: U.K. gives Russia a deadline to explain nerve attack
British Prime Minister Theresa May threw down a gauntlet against Russia today, telling the House of Commons:
"The [British] government has concluded that it is highly likely that Russia was responsible for the [nerve agent] act against [Russian former double agent Sergei Skripal] and Yulia Skripal [his daughter]."
May said that Russia has until Wednesday to provide a credible explanation, or "we will conclude that this action amounts to an unlawful use of force by the Russian state against the United Kingdom."

Be smart... Axios' Steve LeVine, author of Putin's Labyrinth, which focuses on the murders of Putin's enemies, says May will be in a political box if a Russian role is found:
[The 2006 murder of Alexander] Litvinenko caused a huge international incident and a lasting diplomatic breach. If [the Skripals] die, this will be murder, again, in a major Western country. The Brits could cut off relations, recall their ambassador, and so on — to which Putin would protest, "show us the facts. The West again is hysterical" — but May will be forced to take demonstrably stern action. Against the backdrop of Crimea, one might see her seek an EU-wide response, though given the changing politics on the continent, that could be hard to achieve.
