Putin is the most powerful man in the world without a doubt!
It's not what the man have in his disposal(army, money etc..) it's more the way he acts and thinks, he does whatever he wants whenever he wants and ignores the whole world.
Not so true Bro, he can do all he wants because what he had have in his disposal likes money, gold, oil, gas resources in his land & his huge large + modern army
If we talking about what he acts & thinks like doing whatever he does whatever he wants & ignores the whole world then I believe any extremist leader then the real one who really really powerful, since they can spread terror & destruction & hardship & pain & nightmares upon everyone including even the most innocent ones without mercy & regret by spreading their twisted logic + foul imagination + lies + slander + extreme radical revolutionary violence view, for example like ISIS big boss
These extremists even dare to not only ignore the world but even the God & any good human norms, just to sate their greed for power & hegemony
Putin can do all he wants to do now because he is the Russia big boss... but if he just nobody or like us who are mostly civilian, surely he would never capable to do all he wants like now, if he wants to live longer, due to the hardship of life in Russia
