Thanks but still the 330 does not include any new wall so rebuilt and improved.
I so not understand why we are go obsessed by this bollard construction when the Saudis and others have shown that double fences with no-man’s land and sensors are very effective. Ditto with the Indian-Pakistani border fence. Ditto with the expedient but apparently effective barrier the Hungarians built. Why must we spend $24mm per mile for bollard in difficult ground? Looks awfully gold plated to me.
“but still the 330 does not include any new wall”
No, that’s not true. The 330 will include about 100 miles of totally new barrier, where none was before. Most of it will be in Rio Grande Valley. About 90 miles of that was directly funded by Congress.

The threats we are defending against are different. Their border is sparsely populated - there is a lot of time and distance to intercept intruders. They post a lot of personnel along the entire length of their border, which is a hugely expensive annual cost.
We have more heavily populated areas along our border (including major cities like San Diego). In those areas, intruders can disappear very quickly - sometimes under one minute. Our barriers face frequent attacks with power tools and vehicle ramming, and are subject to mob rush tactics (like the caravans), which can tear down chain link style fences).
In rural areas, our defenses will be more based on on reliable detection and tracking, like the Saudis emphasize in their rural areas, but we still want the strength of bollards to withstand vehicle ramming, anywhere that the terrain is vehicle passable (which includes a lot of desert).
