Today's history lesson.

Did Ukraine teach President Trump how to deal with Turkey?

The MSM frequently complains about the "rudeness" of President Trump, especially in his recent letter to Erdogan. Ha! That's nothing compared to what the Ukrainian Cossacks did to the Sultan of the Ottoman Empire back in the day - talk about hate mail!

To make a long story short, the Cossacks and Turks periodically fought each other for supremacy. In 1676, the Sultan sent the Cossacks a letter demanding submission to his rule. The Cossacks replied and were immortalized in a painting (see related pic).

The Sultan's letter:

Sultan Mehmed IV to the Zaporozhian Cossacks
