This is a national security matter. Declare it one. The drugs, violence and potential for terrorism make it so. As stated, the Dems will do all in their power to hinder via legislation/lawsuit/media the BP/NG/ET all. This cannot be allowed.
The fence does not have to be mid river. At most it requires 300 feet of shoreline for fence/road/open security area. If there was ever a legit use of eminent domain, this is it and most, by far of the land in question is federal/state anyway. Any farmlands can simply have a canal diverted from the river in those areas for livestock etc.
Animal crossings can be established at and/or neat the manned outposts. Placing one every couple miles with cameras/sensors will take far fewer people to man than Perrys paroling ideas.
The private lands can easily be compensated for at market value since this gets paid for by ENDING monetary aid to mexico.
So, lacking specific details is the basis. Canals are farmer maintained, Border crossings are where they exist today.
People saying the terrain is too rugged need to explain how china did it 3000 years ago over terrain with far rougher features and nothing but human hands.
Those are some good ideas that should be considered. But I didn’t say anything about the terrain prohibiting a fence.
The fence does not have to be mid river. At most it requires 300 feet of shoreline for fence/road/open security area.
I believe there are some requirements about fencing/walls along the flood plain which must comply with US/Mexico Treaties, Rio Grande/water.
