as one of the americans in that discussion, I must say again what I said then its all what you grow up around. if you look at the older generations that have seen war they aren't freaking out as much cause they've seen real war, they know the actions that lead to it. (Not saying IF or EF aren't real wars)
but the thing is now you can't be sure what's propaganda and what's just civilians blowing out of proportion. I have to agree that the chances of Russia starting a war are slim, unless instigated to that point, we're more likely to go back to Iraq or fight North Korea before we fight the Russians,
To respond to a earlier point as well on the NATO joining to defend or attack, the U.S has done that for our current conflicts in the middle east when we were hit on sept. 11 but again NATO is a lot of talk with no real willpower behind it because no one nation wants to foot the bill for starting a war over something.
the way I see it as we wont go to war with Russia unless: A, a asset that is deemed "needed" by our government is withheld from us. B, they do something that our public has an outrage about(attacking another nation.) or C, a Direct attack on America.
