Normally when you think of the strongest world leader you think of who has the most power politically not in this case. In this case I/m talking about the strongest physical world leader. Personally I'd have to go w/ Vladimir Phutan, prime minister ( he's basically stll running the country) of Russia because he does Judo, so what do you think. *( Oh, and it doesn't have to be a country's leader could be a senator,symbolic monarch, etc.
Hitler, not saying i think he was a SANE leader, and not to mention one that i'll never agree with was a very stronge and devoted person who could rally hundreds and then thousands at his will. that requires a very "strong" leader to accomplish such feats.
Currently I say Vladimir in the Past I say Hideki Tojo he got all of the Japanese to beleive that they could be samurais if they would do suicude charges at the enemys as long as they killed some they had planned to have the civilians to attack american troops with sharpened off bamboo if america would invade Japan.
do they have to be alive now or could it be some one from the past? any ways, if it can be some one from the past then hitler, no offense to any 1, i know he did bad things but he was a strong motivational speaker. and i dont know much about todays people, definatly not bush though.
