What country do you think is the most powerful in world today?

i think none of the above. because 1 country cannot do things on theirself. if country A wants to do something that is unheared of. country E,F&G will say no you can't do that or we will stop our "friendship" or if country B want's to attack country A; E,F&G will help to protect A. so you can't say that their is a most powerfull country, because in the end they are all nothing without the support of others
