Excellent point:
The Guinness Book of World Records contends that the largest anti-war protest in the history of the world was a protest against the Iraq War. Millions are not flooding the streets of Rome, London, Barcelona, and Sydney to protest the Russian aggression in Ukraine, nor its prequel four years ago in Georgia. They’re not protesting Assad’s actions in Syria, nor North Korea’s increasingly regular firing of advanced missiles. They yawn as China runs military exercises that look suspiciously like a training run to seize the disputed Senkaku islands from Japan. No, American military action is deemed uniquely bad and worthy of protest.
Fine. Forget the shields. That's probably more dangerous than parking yourself in a Baghdad kindergarten classroom or kitten shelter. But what about simple outraged protests and maybe a rhyming chant or two?
You have to admit, it is far safer to express outrage against America. These "anti-war" protesters may be fools. But they're not stupid.
