Abstract: In recent years, India-US security cooperation has accelerated, overall defense cooperation framework has become increasingly mature and has been continuously updated with the times. The scale of India’ s imports of weapons and military supplies from the United States has continued to expand, and India-US joint military exercises have deepened. Since the Modi government took office in 2014, it has signed two basic military cooperation pacts with the United States, paving the way for further upgrading the two countries’ defense cooperation in the future. India-US counter-terrorism cooperation is starting from scratch and continuing to deepen, further expanding the contents of their security cooperation. India-US close security cooperation has had a serious negative impact on India’ s overall foreign strategy, especially its tradition of long-standing strategic independence. It has eroded material and institutional foundations for India’s strategic autonomy, and deteriorated India’s geostrategic environment, which is not conducive to realizing its dream of being a great power.
