1,400-mile Maginot Line
Maybe after enjoying this respite, however brief, the people in the area will be more demanding of washington. I couldn't live like this.
That's not a dig at the French. The Maginot Line is the ultimate symbol of a seemingly strong but futile defense, so the writer is implying that our defense of our border is likewise futile.
It's not really a very good comparison, though. The Maginot Line was not breached, but skirted. Also, the storyline is a lot different. The Maginot Line stood unchallenged for some time and inspired a false confidence in the security it seemed to provide. Our border with Mexico is and has been so porous that it inspires not confidence, but frustration and outrage.
