Scaring people during Covid worked well. With EU elections approaching they want to inflate a similar worry about war, for people to vote for the same bunch, hoping for « a reassuring stability ». Plus, this is just an additional way to grow the debt as they’re broke, and continue enforcing EU-level governance. Macron doesn’t see the value of a (French) state, so influenced he is by US who tells him & EU what to do, in economics, war and energy.
