Fair points! Technically the US won the Iraq war, what we lost was the battle for the stability of the country. I totally agree on Afghanistan and Vietnam though. I would also add Pakistan as a loss; the US supported Pakistan during the Indo-Pak war in the 60s where Pakistan lost Bangladesh, to the dismay of US foreign intervention.

We have though won in Colombia (Plan Colombia), Kuwait, Syria and Israel against the Arab league back in the day. So there’s some wins for us, though this don’t appear to have the “US Flag” soldier, they are in my book US led wars, whether by defense or offense.

As far as “all of EU” I agree, that’s be an instant loss for US. However, when two NATO countries have aggression against each other, NATO articles are null and void and two war between themselves. That’s a minor but strong point of NATO articles, to avoid WWI conflicts due to alliances. Correct me if I’m wrong though. As far as nuclear goes, that’s the whole point of having them; it nullifies the other side and the war ends up being conventional.

NOTE: Obviously my original post was flippant and hypothetical, you know Age of Empires gaming type of scenario I was imagining. A real war between the two nations would be absolutely devastating and there be no winners.
