I don't know why they would be afraid. The American people will do nothing about it. Would love to be proven wrong.
Their cash flow is being steadily dried up. Unions can't drain taxpayers now, and the tax dollars going to liberal groups from EPA, State Dept, and Housing are all shut down. Several liberal leaders are possibly hours away from indictments. Rosenstein supposed to be impeached this week, I think. Trump is forcing the Europeans to abide by their own laws and agreements; e.g, Brexit, NATO support, etc. Stirring hate and misunderstanding is all they got right now.
The American people already did something about it. In fact they did the best possible thing available to them. They elected President Trump.
