If you want to go on believing that a nation which sent men to the moon 35 years ago cannot control a border that's your prerogative, but what I suspect is you don't really want to see that happen, you prefer millions of people pouring in and enjoy making excuses for them.
"but what I suspect is you don't really want to see that happen, you prefer millions of people pouring in and enjoy making excuses for them."
what you suspect or believe is allready pretty suspect - and I have NEVER made excuses for them, but I deal in reality.
But I have more faith in the US then you, we WILL solve the problem, just not in the isolationist fashion you suggest.
