Friendly War

You should recognize the power that I hold,
And why the path I walk is lonesome and cold.
I am the high king and you should know
I bring rain to the desert, and to the tropics I bring snow.
Understand that the world changes by my hand.
Against me all fall. My enemies no longer stand.
Don't offend me because I detest conflict,
But when you wrong my friends my decision must be strict.
So if you ever find time to raise the red flag,
Down my stone steps, your body I will drag.
