Wildflowers.

Ask the wildflowers
When the fires burn everything
If they would return

Ask Joseph or Job
Jonah in the whale's belly
If succour would come

Ask the zookeeper 
Blames he the wounded tiger
For his missing thumb?

When the churchbell tolls
The end of life, at God's will
The son must throw first

When flames are bitter
When the oldest oak withers
The wildflowers wait.

There is light at the end of the tunnel. Whether it is another train is unknown, but for now it beckons bright all the same. 

I love how Haikus challenge you to express what would take 2-3 stanzas in three short lines, and a poem of Haikus can pack a lot in very little.

I wrote this listening to Miami 2017 (Seen The Lights Go Out On Broadway) by Billy Joel. It's such a wonderful song and I think the detachment in the song's viewpoint of disaster is what set the mood.
