Why, 10,000-plus miles of border of course! Hey, the Maginot Line worked so well for France, didn't it?

How many people walked across the inter German border during the Cold war? Oh borders can be sealed, or at least controlled. It just takes the desire to do so.

How many people walked across the inter German border during the Cold war?

False analogy. With the economic situation in East Germany vs. West Germany during the Cold War, the walls and concertina wire on the East German side were there to keep people in, not out. And the folks on the West German side weren't shooting at people on the East German side trying to get out; in fact they actively tried to help people cross.

Oh borders can be sealed, or at least controlled. It just takes the desire to do so.

I keep hearing that. Just like I keep hearing that we should "defeat evil". Both laudable goals, both pretty much unobtainable at our present level of technology.
