  1. Nice cataloging. There was also Shay’s Rebellion in 1786 along with numerous other small uprisings that were largely taken on by state militia. And we were chasing Geronimo and the Apaches all over the southwest in 1885-86–we had five cavalry regiments (some 5,000 troops) chasing about 40 tribesmen. We’re a terribly bellicose bunch. And prospects are lousy.

    • Morning, Dan.

      I only listed military actions that lasted about a year–maybe three quarters of a year at least. Therefore Shay’s Rebellion doesn’t make the lists. I left out a lot of events because of this standard.

      And yes we are a bellicose bunch – by my calculations the U.S. has spent less than 8% of its lifetime at peace. It’s harder to gauge though because unlike for example, the Israelis, who if they are at war, the whole country feels it strongly, we have wars that the public hardly notices because of the combination of a massive population and relatively small percentage of that population that actually enter the military and fight.

  2. You’re stretching the term “at war” beyond reasonable boundaries here, Phil. While it would be fine to list Vietnam and Korea as cold-war actions, the “cold war” itself was a decades-long period of military build up and brinkmanship, not one, ongoing military conflict. Also, you seem to include conflicts in which the US provided training, funding or support for one (or both, in the case of the Iran / Iraq war) sides, but took no active military role. To list the Russian Civil War, the Mexican Revolution, and the Boxer Rebellion as US wars is absurd. Why not the War on Drugs? The War on Christmas? Anti-piracy actions don’t really qualify, either. I think a more honest way to make this timeline would be to call it “American Involvement in Conflict” and to make clear the level of that involvement. Furthermore, I would divide it into sections like Independence, Unification (civil war), National expansion (Indian wars, 1812, Mexican American, Spanish American, Phillipines, etc.), Empire building (piracy actions, Banana wars), Geo-Political (WWI and II, cold war actions) Humanitarian (debatable), Geo-Strategic (middle east conflicts) and so on. There would be a lot of overlap, obviously, but you get the point. I would also parse out the conflicts where the US was not a direct player, but fought through proxies, as was the case with many cold war actions, and those cases where involvement was minimal, and limited to funding and/or political support. Anyway, a good effort, and a good start, but calling all military actions “wars” isn’t useful if we’re looking to compare American militarism with similarly sized empires throughout history. Every large empire exists in a near constant state of military action. That’s the nature of the beast.

    • You’d have to be the most stupid hispanic on the face of the earth, to even debate those statistics. This republic was founded in rebellion, and we have been the most rebellious nation in our short existence. And I grieve for our future. We’ll all be in sackcloth and ashes bemoaning our fate real soon

  3. Edit: I’m editing my response because I just reread it and I sound kind of cunty. :)

    I strongly disagree, Dan. The cold war was one elongated conflict, fought frequently through proxies where American “advisers” were on the ground and actually fighting themselves, which is why I include El Salvador and Nicaragua in my thinking for example.

    You may have a point about the Iran/Iraq war, although research seems to indicate that while the war lasted over 10 years, between 1987 and 88, the United States did take military action with operations Earnest Will and Prime Chance, both naval actions. Regarding the Russian civil war I believe you are again wrong. The Siberian Intervention and the North Russia Campaign both had Americans (and other allied forces) on the ground fighting against the Bolsheviks. [editing out this douchebag statement of mine] over 8,000 American troops were landed in Northern Russia for this action while nearly 10,000 were on the ground for the Siberian intervention.

    Regarding the Mexican Revolution the United States had boots on the ground twice. First during the Ypiranga Incident and then again with the far more famous chase Pershing had through the Mexican mountain ranges for Poncho Villa. Both actions were failures from the U.S. point of view, but there were American boots on the ground in Mexico nonetheless, and not just dozens, but thousands.

    Regarding the various anti-piracy engagements, particularly that of the Barbary Coast, but many others; when the U.S. Navy is involved in action, American sailors are dying, and specific military objectives are stated, that sounds like military action to me. Not as hot a war as either of the World Wars, but no less a military engagement.

    Finally, regarding the objective of this piece [edited for douchebaggyness again] was to figure out just how many years the United States has been at peace since its inception; a grand total of 24.

  4. I applaud your attention to detail, if not your conclusions. The problem with your methodology is that you define “at war” as any conflict in which US personnel are involved, equating the CIA in central America with Patton at D-Day. Meanwhile, you define “at peace” in the narrowest sense, basically stating that the only way to qualify is to have no involvement whatsoever with any conflict, anywhere. This is a false distinction.

  5. I’m pretty specific in delineating just what I consider to be worthy of the list. The parameters are: A military engagement of some kind that lasted at least 3/4ths of a year. The term “at war” is only by itself in the title-and that only for marketing purposes. In the body of the post itself is the explanation. You may have skimmed over those points in your excitement to peruse the list of conflicts I provided :)

    One other issue made the research slightly more difficult: Namely what a “sate of war” is in the U.S. We both know that Congress is supposed to govern whether or not we go to war, but congress seems to have allowed that power to atrophy since the second world war. As a result I have had to decide on my own which military engagements qualify for the list I provided. You may be right that the parameters I’ve set are too broad. I’ll give it a think.

    What parameters would you use, Dan? I should add that I really didn’t have any intention at the start of the research beyond my own personal curiosity. But as I did the math, adding up the years that the U.S. wasn’t involved in a conflict–well, my jaw hit the ground when I was finished.

    I’d be curious to know which engagements I’ve listed you think I ought to have left out. Besides the Russian/Mexican revolutions, which I think are warranted (we’ll just have to agree to disagree) and actions that are strictly naval, like the pirate actions.

  6. I would limit the list to conflicts in which the US made substantial contributions of men and materiel, and have a separate list for small, short-lived operations like Somalia and Bosnia.

    • Dan: I agree with Phil–the US support of the Mensheviks in the Russian Civil war poisoned the well for generations. Ditto our take-out of Pancho Villas. And the image of then-lieutenant George Patton driving back to command with two of Villas’ dead lieutenants strapped to the hood of his car like deer didn’t endear us to the locals. we also intervened in the Dominican Republic in the 1960’s when the locals elected someone we didn’t like. Just saying.
