The games go back to ancient Greece,

Where city-states would keep the peace:

No fighting in this interlude

While men would wrestle in the nude.

We might no longer honor Zeus

But, yes, there's an Olympic Truce

Decrying violence, war and death.

Good luck with that; don't hold your breath.

In Rio now, where tourists stroll,on patrol.

Thefts and muggings, a way of life

(Some at gunpoint and some by knife).

And then toss this upon the plate:

Hints of terror, Islamic State.

But yet the mayor makes it clear

There is no safer place than here _

A claim Greeks might not understand

For peace, it seems, is not at hand.
