On Wednesday, the UK Government said it is charging two Russian military intelligence officers with the nerve agent attack in March in Salisbury, England, attempting to kill former spy Sergey Skripal and his daughter Yulia.

The question now moves to “Can the Russians bluff this out and avoid further diplomatic and economic punishment?”
