Which one is stronger, words or actions?

I would say that they both is very stringe and powerful, but I would mostly say that action speaks louder than words, because George W. Bush was saying how he was going to make changes. But it took B. Obama to speak and do action, and it moved the whole world. At the same time words are stronger, because Martin Luther King Jr. spoke out to the world with words not actions, and he had something to do with "CHANGE" with in todays society. Both words can be very powerful, depending on how you use it. Action can really be powerful, and stronger than words, because say if someone wanted to fight you. By them saying they wanted to fight you is diffrent than really fighting you.
