Last 100 years ? That ' s a shit question 1 . America has been a hegemonic state for at least 100 years , so asking this questions opens up pretty much addresses everyone 2 . The development of the atom bomb changed the whole world you spankhead , not just individual countries , so a better question would be to focus on particular events or particular times , not just the last 100 fucking years you walnut . 3 . Fucking google foreign policy . Almost Every president has had different foreign policies , so this is like asking how nonAmericans have been affected by politics in general . I wish I could punt you right in the gaping hole between your two slowly dieing brain cells . 4 . Thundercunts like you mean the rest of us are forced to think about completely ridiculous questions , so thank you very much you twatasaurus rex .
