He's not serious at all
Yes, Vladimir Putin is not a serious person - of course.
Your president, who doesn't respect anyone, still respects Putin. The leader of China flies to attend his military parades personally - totally not a serious person.
Has tens of thousands of Chechen cutthroats at his beck and call - not serious at all.
Sends ministers to sign economic agreements worth hundreds of billions, because it doesn't merit his personal attention - not serious at all.
Sends hundreds of thousands of men to their death with his orders - not serious at all.
Your Time magazine has called him the most powerful man in the world. I wonder, who for you is serious. Come down from the clouds perhaps, and touch some grass.
I have a very inflated sense of self, but I would never dare to compare myself to Putin.
