However, they warn against generalizing that the fence is the sole reason for the drop and raise objections in comparing Israel’s border issues to those in the United States.
The success of barriers such as a wall or fence depend on their scale and how heavily guarded they are, said Reece Jones, a political geography professor at the University of Hawai'i-Manoa and who has written about money spent on border security projects and their consequences.
On a small scale and with many guards, walls can effectively stop movement, Jones said.
But Israel and the United States’ southern borders are significantly different.
The Israel-Egypt border fence is about 150 miles.
The U.S.-Mexico border is nearly 2,000 miles.
Terrain conditions and number of agents needed to monitor the border are not comparable either, Jones said.
"Most of the Israeli fence goes through open, arid terrain. Easy to access, easy to build, easy to monitor with agents," Jones said.
The U.S.-Mexico border, on the other hand, includes very remote, mountainous terrain and spans the length of four states with cities closely intertwined with Mexico. Trump has said that border has 1 million legal border crossings daily, which experts have told us include people traveling back and forth for school, work and shopping.
