Putin: It's my party and I'll invite whomever I want to
Dear Jong-un,
You are invited you to Moscow for a little bash I'm having in May. And by "little" I mean the greatest ever. Check it out: Biggest military parade in the history of military parades, where you can see up close all the new products and mark down a wish-list, synchronized marching which you love-love-love, lots of foreign leaders who are going to be royally pissed with you there (yeah!) and a complimentary mobile cheese buffet at your disposal 24/7, no expenses spared, no questions asked. See you there.
Your new BFF,
Vlad
