The Barking Roof Dogs - explained

When I was 17 and pregnant I lived in "Highgrove" Riverside County, California.  Our studio apartment was on Iowa Avenue and between  4:00 - 6:00 PM every weekday it was gridlocked. 
Up the road at the main intersection there was a row of homes. Flats, really. One story flat roofed homes. One of the homes had a lot of junk and rusty cars all around it. A pair of mid to large sized dogs had climbed the piles of junk onto the roof and they stood there barking - incessantly - at the traffic waiting on the light. I realized later they did this every day. 
Those dogs just standing there atop their house of what looked like worthless junk  barking (bitching and moaning) at people on their own paths, doing something, going somewhere, became a metaphor for so many people that stand on their own pile of crap spending their energy barking at and about other's that are mostly inconsequential to them but unfortunately close enough to be noticed by them. We've all been a roof dog at one time or another, some briefly, some incessantly. 

Barking to biting?

Is the U.S. the worst kind of roof dog? 

This translated from a Russian news website: B View/Reservation for Kerry :

Damascus agreed to call Moscow and Washington to transfer all of its chemical weapons under international control. Earlier, U.S. Secretary of State, John Kerry said that in this case, Syria could avoid the bombing. Reservation Kerry suddenly caught Moscow, and then supported and London. However, experts believe that for Syria, and for the United States is nothing more than a rhetorical device designed to maintain a reputation.

Our government barks... and bites. Should we strike down Syrians for striking down Syrians? 

Does that make sense? Not to me.
