While scholars have made many claims about US military interventions, they have not come to a consensus on main trends and consequences. This article introduces a new, comprehensive dataset of all US military interventions since the country’s founding, alongside over 200 variables that allow scholars to evaluate theoretical propositions on drivers and outcomes of intervention. It compares the new Military Intervention Project (MIP) dataset to the current leading dataset, the Militarized Interstate Disputes (MID). In sum, MIP doubles the universe of cases, integrates a range of military intervention definitions and sources, expands the timeline of analysis, and offers more transparency of sourcing through historically-documented case narratives of every US military intervention included in the dataset. According to MIP, the US has undertaken almost 400 military interventions since 1776, with half of these operations undertaken between 1950 and 2019. Over 25% of them have occurred in the post-Cold War period.

尽管学者们对美国的军事干预提出了许多主张，但他们对主要趋势和后果尚未达成共识。本文介绍了自建国以来美国所有军事干预的全新综合数据集，以及 200 多个变量，使学者们能够评估干预的驱动因素和结果的理论命题。它将新的军事干预项目 (MIP) 数据集与当前领先的数据集军事化的州际争端 (MID) 进行了比较。总而言之，MIP 将案例范围扩大了一倍，整合了一系列军事干预定义和来源，扩展了分析时间线，并通过历史记录的每个案例叙述提供了更高的采购透明度数据集中包含美国军事干预。据 MIP 称，自 1776 年以来，美国已进行了近 400 次军事干预，其中一半是在 1950 年至 2019 年期间进行的。其中超过 25% 发生在冷战后时期。
