The centerpiece Donald Trump’s announced measures to deal with COVID-19 is a travel ban from Europe.
This is the administration’s default response to any situation:  Build a wall.

In this case, the wall is the Maginot Line:

Donald Trump announced that the US would temporarily suspend all travel from the European Union, as the country reckons with the spread of coronavirus and the White House grapples with the severity of the situation.

The restrictions, which would begin on Friday and last for 30 days, would not apply to the UK, he said. He also encouraged older Americans to avoid all travel if possible.

Trump made the announcement in an Oval Office speech on Wednesday evening on the federal response to what the World Health Organization has declared a global pandemic.

During the speech, Trump defended his administration’s response while laying blame on the European Union for not acting quickly enough to address the “foreign virus”, saying US clusters had been “seeded” by European travelers.

Seriously, this is f%$#ed up and sh%$.
