It’s terrifying to see it visualized like that.
Deportation of “homegrowns”. He’s not exactly subtle about it. Watch out for talk about violent criminals being too dangerous to be allowed to stay in America.

The Insurrection Act of 1807 allows the president to use active-duty military personnel to perform law-enforcement duties inside the US.
Once invoked, troops could be tasked with a range of duties, from quelling civil unrest and enforcing court orders to arresting and detaining migrants.
Because the Insurrection Act was written in broad terms, with little specific guidance on how and when the powers can be used, it gives presidents wide latitude in deciding when to mobilise military personnel for domestic operations.
Time to bring in the army to oppress the citizenry. Hoo rah!
I dread the elections in France in 2027. France is one of the last bastions of Freedom that is capable of standing up to the authoritarian states if push comes to shove. The last few presidential elections have moved France closer and closer to having a Kremlin sock puppet in charge. While they have managed to pull back from the brink a few times, it only needs to go wrong once.
I think you have a much higher opinion of French political culture than is warranted.
