That’s the whole point. How come India can put up a fence, light it up, patrol it...but we can’t?!? Their terrain is all the way from the Himalays to the deserts of Rajhistan. Makes no sense!
Now, having said nice things about India, I have to also say how deeply embarrassing it is to find that India seems to surpass the USA is some basic areas. We really do seem to be a third world country these days.
It’s not a matter of being able to. It’s a matter of *wanting* to.
