I never suggested there was an open border policy to the greater world when it comes to the EU/EFTA.
Only that the U.S border cannot in any way be called an open border, as it does not allow free movement of people and goods across its borders when arriving from another country.
While selective in who it is open for, the Schengen Area can be called open as it requires no visa's or passports and allows complete freedom of movement for citizens of those countries that have signed up for the agreement.
