Obama To Belgium: We Have Your Back

What does it mean when U.S. President Obama says "we have your back"?  What does it mean when he brags that he "leads from behind"?

Perhaps the Belgians could ask Libya, Egypt, Tunisia, Iraq or Afghanistan.  Today, President Obama is leading from behind in Syria.  To Syrians it means 10000 bombing raids and 30000 bombs dropped on their cities.

The Belgians should contemplate the damage done by 10000 bombing raids over Belgium.  Obama has your back?  My advice?  Duck.
