"Your plan for solving the problem"
hmmm, catapult?
No, seriously now....what are you going to say when WMD gets smuggled across the border and used to kill by the 100's of thousands? You will say, "gee maybe we should discuss sealing the border"
They used to call that closing the barn door after the horse had escaped.
Explain how you would seal a 2000 mile border. Please include estimated manpower and cost, as well as a timetable.
If that's the intended mission, you've just set a performance criterion that must be met:
100% success.
Please give us a plan that would accomplish this goal.
