Is global peace possible ?

no, nothing is perfect, especially not our world. Maybe in a movie. Good cannot exist without condition.

I agree with mainframe, so long as good/evil, greed and corruption exists

No. Generally and never. Friendship between humanity will never be. Man is designed so that he will always look for a trick

Global peace will never be happened cause there are to many different people and you cant make them happy at all. Its simple as it sounds.

Define peace. Not open war? Then there is peace between North and South Korea.

I know what you probably meant and it's basically impossible as long as people are, well, people.

No well in my opinion nothing is impossible but in this situation there will always be that one person who ruins everything so if you are talking about 100% world peace then no. But peace between countries yes.

There is a reason peace is only an ideal utopian dream rather than what we can achieve. Humans have continuous rifts with everyone that peace only becomes a temporary option.

Its not possible because money and force are the reasons. Without that is it maybe possible.

honestly global peace is possible, but it will take a huge event! like alien invasion where after the after math is so dramatic that we decided to unite... ya know...
