A striking caption from one of the images in this gallery

> This monastery was occupied by the Germans, most monks escaped to the Netherlands. The wire was build right through the monastery's yard, all 2.5 km of it. The monastery had to pay for the expenses.

The parallels to someone yelling about building a wall and having Mexico pay for it is chilling.

No it doesn't

Comparing a wall and a wire that electrocutes you is ridiculous.

It really isn't so ridiculous. Walls are often topped with razor wire or electrified wire. Even if "Trump's Wall" isn't planned to have that now, it may have it after a few escalations.

If there were a catalog, they'd be on facing pages.

edit: Why am I trying to be pithy here? If you need to think a wall is so different from a fence is so different from an electric fence, you're rationalizing something.

Damn right.

I'd imagine you'd need to relentlessly patrol the wire for it to be effective. The barrel method, as seen in the pictures you linked to, seems to be an easy way to defeat the wire.
