“Comparisons to China and Israel are strawmen.”
No. They are not. Please show exactly how they are or retract.
The Great Wall of China took well over 300 years and 500,000 men to build. The United States is not quite 240 years old itself.
Israel’s separation barrier is approximately 400 miles long, which is one-third the length of the Texas border and one-fourth the length of the U.S. border. The terrain in Israel does not include 1200 miles of water. The barrier is primarily intended to prevent terrorist attacks. The Arabs are not digging sophisticated tunnels under the barrier complete with electricity and rails to transport drugs and illegal immigrants.
Different purposes. Different terrain. Different resources. Different time periods.
