U.S. Will Tighten Passport Rules writes The Washington Post. Passport rules for United States citizens are meant, not just for foreigners. In future, when traveling to Canada, Mexico or the Caribbean, U.S. citizens will only be allow a return to the States, when they have a valid passport. A driver license will no longer be sufficient.
Other parts of the world are opening their borders and make it easier to travel. In Europe the Schengen agreement allows the people to travel between fifteen countries, and more in future, without any border controls or passports.
This type of Homeland Security makes me wonder what the administration really anticipates to be a security risk.
In fact I think the singularity of 9/11 is not the reason for this, it is rather the excuse. It is another step in a new isolationist wave in the U.S. that will develop far further than we now imagine. The real reason behind this is the fear and uncertainty of a falling empire. Emperors do not need passports.
