Siege diplomacy 
Globe and Mail (Canada), 10/6/2008 

The Globe and Mail criticizes the change in the United States' approach to diplomacy and embassies, citing "a worrying trend toward vastly scaling down American public diplomacy abroad, abandoning embassies that were once beacons of American culture and openness in favour of walled suburban fortresses. . . . Security concerns can be addressed within attractive and accessible structures, and Washington should think long and hard about what a new generation of embassies that ignore this fact will say to the world about the United States."
