Under Ottoman Empire treaty with Catherine the Great if Crimea declares independence it returns to Turkey — Headline from the Voices of Ukraine website

Attention all dictators with imperial ambitions

Conquests often come attached with footnotes and conditions

 

There isn’t any nation so disorganized and poor

It doesn’t have a lawyer on its diplomatic corps

 

The country you annexed or stole or conquered in a war

May be subject to a treaty from two centuries before

 

The Caucasus are full of little quirky traps and snags

So better do a Google search before you plant those flags.

 

Going back in history the records may get murky

And so a word of caution for the bureaucrats in Turkey

 

If you claim Crimea and decide that you should press on

Prepare to get a letter from the heirs of Kublai Khan
