Here is more from Politico:
When Justin Trudeau meets Joe Biden at the G7 summit in Italy this week, Trudeau will probably not ask whether the United States is at risk of erupting in civil war in the next few years.
A think tank housed within Trudeau’s government is already pondering that question.
In a spring report titled “Disruptions on the Horizon,” a quiet office known as Policy Horizons Canada proposed American civil war as a scenario that Ottawa should consider preparing for.
This hypothetical was tucked into the middle of the 37-page document, which sketched the possibility in 15 spare words: “U.S. ideological divisions, democratic erosion, and domestic unrest escalate, plunging the country into civil war.”
Dr. John McArthur, a Canadian citizen and Senior Fellow and Director of the Center for Sustainable Development at the Brookings Institution, sits on the Policy Horizons steering committee and is the only US think tanker to do so.
