A small group of anti-war demonstrators staged a peaceful “die in” on Thursday at President Barack Obama’s election campaign headquarters in Chicago to demand an end to the war in Afghanistan and unmanned drone aircraft attacks overseas.

Despite calling ahead, some of the roughly 50 protesters said they were unable to deliver a letter to the Obama campaign calling for the United States to leave NATO and its “violent mission of protecting the 1 percent in the global economy who represent 99 percent of corporate wealth in the world.”…

“We are here speaking out against war and militarism. We are calling for NATO to be dissolved,” Leah Bolger, 54, from Corvallis, Oregon, said on Thursday. She wore a shirt with a dove on the front and “I hate war” written on the back.

Amid a carnival atmosphere on a warm, sunny day, about 10 protesters pretended to be killed by a cardboard drone aircraft painted silver and held aloft by a demonstrator who also provided sound effects. The protesters’ bodies were then outlined with pink chalk.
