Looks like we're throwing all that out the window in favor of a new arms race. Only now we're spreading the fun to other planets too. This is a prelude to making claims on extraterrestrial bodies and then fighting wars over them; don't be naive.
We are going to have a space capable military, but that doesn't mean we are 'militarizing space'. We aren't putting nukes in geostationary orbit above China or building rail-guns on the moon.
And which countries outside of the US would you suggest I look for this peaceful utopia? Somewhere in Asia, Africa, or South America? I'm not sure Australia is the best example. And please don't suggest socialist Europe, who have committed some of the worst atrocities known to man in the very recent past.
It is extremely naive to think that the majority of society's aggressive tendancies can be blamed on a handful of ruthless leaders or sociopaths. If that were the case, this would be a simple problem to solve. The much tougher truth is that we each have a piece of this inside of us.
