There was almost a party atmosphere among anti-Nato protesters who turned out in central Chicago as the summit drew to a close.
Unlike earlier rallies where clashes with police had led to injuries and at scores of arrests, demonstrators just wanted to get their message across.
This time their target was Barack Obama who was criticised for his administration’s spending on defence.
“The whole hope and change dialogue was so prominent in his campaign (Obama’s) and yet there’s really been so little and we’re still seeing all of this money being spent on security, being spent on various wars,” said one protester outside Obama’s re-election campaign headquarters.
When asked about the protests, President Obama just said people had the right to express their views.
