When it was determined that Russia was behind the poisoning attempt on former spy Sergei Skripal and his daughter last March, England quickly moved to impose sanctions. Since this violates international law, allies are obligated to also impose sanctions on the offending country.

Why the delay? Trump’s ‘friendship ‘ with the dictator Putin. It is a scary world we live in now.
