I guess we have to decide how we define "started". First U.S. boots on the ground? Involvment in Operation Castor? Operation Vulture? Kennedy's troop escalations? The Golf Of Tonkin?
Well, even the definition of war is murky, though you might not expect it to be so. We have definitely been in a lot of conflicts that were for all intents and purposes wars, even though they weren't called that.
Maybe the definition should be narrow: a military conflict between or among two or more nations, formally declared as such by all governments that are involved. So we could think up some other term for such things as Trump blowing up Venezuela, though "assholery" will do for now.
Also, where in the hierarchy of deeds is joining in on an existing conflict, like in Korea, Vietnam, or Kuwait?
