Angela Merkel, the most powerful women of the world

How come?
We believe that Angela Merkel, the Chancellor of Germany, is really a great and experienced leader of her generation. She is making a strategy that is well-considered for the future, although this future is not very clear at sight. So what makes her become a great leader?
Among the scientific magazine Forbes, that is dealing with popularized rankings, "she stuck to her principles, getting G-8 leaders to agree to significant cuts in carbon emissions. Merkel later corralled European Union countries into an agreement on a treaty to replace the E.U. constitution.(see also label European Constitution)". That's a achievement!
We personally think that she is a perfect crisis manager and that for many reasons:
She has proved to have morale principles, in heavy times of Cold War. So she refused to cooperate with the Stasi.
Even former Chancellor Kohl, her protégé, she wishes not to related with, because of rumours of illegal finances of the Christian Democratic Union. From then on, her star is rising. Her method of working with different departments sympathized her with friends AND enemies.
Who's says not: The King (Kohl) is dead. Long live the Queen (Merkel)?
But that happened with her fantastic strategical move in political Germany.
And now she's in China...
