I have been reading alot about Japan and their military submarine fleet.
They are producing submarines at a cost of approximately $2 billion a piece.
Would a US national defense program with a comprehensive MEM sensor system be more efficient?
I believe the metric of the future is not capacity but capability.
A "sensor" system of our nation's borders would secure them without building walls or fences.
I have also heard that in the northern part of our Mexican border there is very little illegal entry so I am not convinced that a "boots on the ground" approach to illegal entry is efficient in that region.
Walls and fences are not American.
Our country is what this is about and securing our borders without building walls should be the goal.
