Or a better question might be, who is going to bring a the equipment to blockade us within 1000 miles of our shoreline and not get blown to bits?
At a particular DEFCON, we don't ask who you are or what you are doing near our shores, we just blow your ass up.
And you think Bill Clinton, who reigned in American for 8 full years, would implement that policy under any circumstances? And I'm sure the first page on any enemy's playbook is to wait until the next Bill Clinton/Jimmy Carter takes office.
