99.9% of the Americans I talk to every day are refraining from commenting about whether the US should intervene in the Ukraine. But, then, I'm not asking.
However, does the fact that if you don't know where the country in question is located, and out of war|no war, you choose war, not strike you as somewhat weird?
I'd like to think most people would always choose no war over war ESPECIALLY if they're uneducated about the situation.
Not that that's what's going on here, but I think that's the image that many Americans have of America's place in the world. It's not especially enlightened, but I don't think the people are warmongers, they probably honestly think it's just the right thing to do and that it would have very little in the way of consequences for anyone. It's the latter part that probably correlates with not knowing much about the world outside America's borders.
What nationality are you, again? :P
Assuming ignorance would fall in the same spectrum compared to other nationalities, you don't hear other nationalities confidently stating their opinions about things they know nothing about.
To be fair, I don't have data to back that up, but I can tell you from my personal observations that people usually refrain from commenting or are reasonably educated about the topic.
Why this is important in this case is because it's largely a matter of geo-politics, and if you don't even know where the damn country is, you should not seriously suggest a certain course of action.
