Great idea, I think the American people will agree.
Now on the builders....
* POTUS can use "force" for 90 days w/out Congressional Approval.
* Declare the border a hostile zone and...
* Order the Coast-Guard to secure it and...
* They ask 8 teams of Seabees to built it 2 per state, start at the borders and meet in the middle.
* Israel is brought in as the design team and consultants.
Tell me how and why this can't work..
