I worked at State Department during the Obama era and into the Trump era. I am well aware that the Obama administration did not impose adequate consequences for prior acts of espionage and aggression such as the Cozy Bear hack on State Dept or Mikhail Lesin getting bludgeoned to death in DC. There also wasn't adequate pushback against propaganda efforts.
The OPM hack is widely attributed to China and is probably the most devastating breach in recent memory. Who knows what the real world consequences of that have been thus far.
Either way ny point is that right now, today, there is no excuse not to act. Unless maybe they still haven't figured out what is happening and who is responsible.
