Jetlegged Hijacks

Triptych Isle
has the shape of an equilateral triangle. 
Towards its geometrical hub
raises a high mountain. 
Its peak presents itself
as the center of the island.
From this peak run three borders
by the shortest way 
to the three base-lines of the shore.
Within the three rectangular countries
live black, white and brown melancholics.

"Why!
Everything in our world has three corners.
How come our countries are square?"

"Abolish the frontiers!"

"Dreadful thought!"
"Heaven forbid!"
"Of that beware!"
