Yes, that is true. But, once, using violence and aggressive methods, all the opposition is wiped, we would not need to use violence anymore. And, then, we could be peaceful? It's like hitting a reset button in a way.
No, what I meant is, the superpowers of the world, Russia, Japan, China, etc are the major countries that spear the wrongdoings but, I feel as if it all started out in the US and, as far as I know, most of the countries compare themselves to the US in terms of how developed they are. So, I think US is a major influence on the major countries of the world. Like, recently, India helped US launch a few sattelites and it became a very big deal. If US does a nuclear test. Other countries would want to do one as quickly as possible, so as to not fall back in terms of development, so, I feel US is the center of development and that every other country try to be like the US. So, if US invades Iraq, saying they are trying to eradicate terrorism, other countries would want to do something similar. So, Russia, China, Japan etc would act on how the US does. And, hence, US is partially to be blamed. If US does something that is actually good towards world peace. I'm sure most of the countries would follow. From the movie spiderman(I think): With great power, comes great responsibility. US has great powers.
Oh, I had no clue about all that. So, I guess US is getting either of those two but, I don't think either of the two are any useful?
