Then you have multiple engagements that require a response from the US government.
Even if it doesn’t break down into a full “civil war”, people could die and tensions could greatly escalate.
He’s playing with fire, and if he isn’t very careful he could easily fumble it and make a mess he’s not prepared to deal with.
