Building a Real and Technological FenceÂ
An alternative proposal is to create an effective fence at the southern border by building physical barriers along stretches of the US-Mexico border that US Customs and Border Protection has identified as especially strategic, along with spending over $300 million to significantly enhance border surveillance technologies and aerial assets to ensure that the entire border is more secure.
The Case ForÂ
Proponents of a combination of border technology and barriers note that many miles of the border are impractical to fence due to difficult terrain or because the border runs along the Rio Grande River. We can get the biggest bang for the buck, they argue, by constructing barriers along portions of the border where it’s most feasible and strategically useful. They argue that the additional technology can detect illegal entries, enabling agents to be dispatched where needed. Proponents note that before the first Trump administration, the Border Patrol advocated for this physical barrier and technology combination as the most cost-effective means of securing the border. They also point out that the immigration bill that, for a time, appeared to have the bipartisan votes to pass the Senate in 2024, included this combination of physical barriers and technology.
The Case Against
As with many compromise proposals, the barriers-and-technology proposal has opponents on opposite sides. Those most strongly opposed to illegal immigration argue that only walls and fences across most of the border provide sufficient obstacles and deterrence. Areas without barriers, they argue, will become the weakest points where crossings will occur. While they may also support technology as an enhancement to physical barriers, these opponents argue that technology cannot adequately replace them.
Others oppose the combined barriers-and-technology approach because they argue it remains too aggressive. They argue that no additional barriers are needed for all the reasons they oppose a wall spanning most of the border. These opponents also argue that increases in surveillance and barriers in recent years have already negatively affected border communities and ecosystems, making them feel like militarized zones where citizens and visitors are under
