Historically India had been a non-aligned country. It had been convenient for India. For instance, India managed to purchase weapons from major weapons suppliers while distancing itself from American or Soviet proxy-wars.
In recent years, India decided to shed its non-aligned posture and decided to move toward the American pole. From 2002 to 2018, India signed GSOMIA, LEMOA, COMCASA. BECA is under process as of March-2020. So, as we can see even though moving to the American pole started in 2002, it was expedited during the present BJP rule.
Why has India suddenly decided to change its non-aligned posture?
