I've said it over and over.
Right, but I don't know how many folks here have had the pleasure of our back and forth yet. ;)
Look at how AZ pipes the Colorado and irrigates/feeds SoCal.
You build it on the American side and divert any needed water. THEN you make crossing points as required and guard them. A first year engineering student could solve any issues that arise because no issue is that hard to deal with in the first place. We ran pipe from Alaska to Louisiana, we went to the moon on a slide rule. We left the solar system. A freaking movie director has been to the bottom of the deepest trench on earth. We build islands in oceans.
Diverting water from the Rio Grande directly impacts our obligations under two treaties with Mexico.
Here is a link to a CRS report about those treaties.
Virtual/strategic walls are what we have now. They do not and will never work because liberals exist. Dem, GOP or Other. Half of AZ has signs in it telling Americans to stay out of 'nature reserves and endangered lands" so that coyotes and drug mules can transport their cargo without hassle. National Guard are sent to the border unarmed and forbidden from actually guarding the nation.
We don't actually have strategic fencing because what we have in South Texas is worthless and pointless. They go over it, through it, and under it. They will always do so no matter what kind of wall you build. Criminals will always find ways to circumvent that which stands in their way. We could spend far less money on enough armed boots on the ground, strategic triple fencing, and better technology and get way better results than a wall.
There is zero excuse for not building a solid wall end to end. We have the ability. We have the know how. We have the engineering. What we do not have is people with determination willing to do it. Rather, they 'negotiate' it away every time it comes up as a serious possibility.
Since Trump has said EVERYTHING is up for 'negotiation', I don't expect him to build it.
But it should be built.
The amount of money spent on the triple fencing thus far has far exceeded any estimates provided before implementation. It will be the same for Trump's glorious wall. I agree that he won't build it. Unless we build a gigantic fortress of a wall on their side and we get all of the water, I say a wall is pointless. We need human intervention with the proper tools and the authority to take action.
