It all raises at least two related questions. First, where are the antiwar protests? And second, where is the press?

In a phone interview, the national coordinator of United for Peace and Justice, which organized some of the largest antiwar protests during the Bush administration, Michael McPhearson, said part of the explanation is political partisanship. A lot of the antiwar protesters, he said, were Democrats. “Once Obama got into office, they kind of demobilized themselves,” he said.

“Because he’s a Democrat, they don’t want to oppose him in the same way as they opposed Bush,” said Mr. McPhearson, who is also a former executive director of Veterans for Peace, and who said he voted for President Obama in 2008. “The politics of it allows him more breathing room when it comes to the wars.”
