[Hillary Clinton’s] most crippling blindness has been to networks, national and global, the threads that bind and have changed society. As David Singh Grewal writes in his excellent new book, “Network Power,” a core tension in the world is that: “Everything is being globalized except politics.”

Grewal continues: “We live in a world in which our relations of sociability — our commerce, culture, ideas, manners — are increasingly shared, coordinated by newly global conversations in these domains, but in which our politics remains inescapably national, centered in the nation states that are the only loci of sovereign decision making.”

The Bush administration has accentuated global awareness of this disjuncture. Connected people around the world were appalled by Bush policies — from the trashing of habeas corpus to renditions — but felt powerless to influence them.

Roger Cohen’s piece in the Times, comparing Obama and Clinton, favorably cites David Singh Grewal’s Network Power.
