I don’t buy it. They might be the best segments we’ve had, so people might have gone to the even more ridiculous segments with vehicle barriers or nothing. But you can see how people scooch right up them. Also, with the segment across the top that means they just need to loop the end of a rope and toss that over, then they can secure a climbing rope. Stand atop a truck and it just a few additional feet that even a short illegal needs to reach to get to the top as well.
If the Israelis’ don’t have them as their security I think it’s pretty certain their solid walls are superior. These bollards more than anything just help the illegal activity. And don’t tell me the unions and managements down there haven’t been bought off either.
"they just need to loop the end of a rope and toss that over"
...same as they would a concrete wall, with a grappling hook. Or more easily, with a ladder.
Mt.Everest is climbed every year by skilled people with ropes.
Bollards stop people as effectively as solid concrete (statistically), but provide greater observation and other benefits as well.
Bollard barriers are being enhanced with additional concertina obstacles, which greatly complicates a ladder/rope attack. Military deployments to the the border have been ordered at least through the end of this Fiscal Year (30 September), and they plan to emplace hundreds of miles of concertina.
