I recently heard of India's first and only foreign military air base in Tajikistan, which is known as Farkhor air base. Can anyone please throw some light on the strategic implications of this. Also,
1) Why India chose Tajikistan for setting up its military air base (is it because of its proximity to Pakistan or any other reason)?
2) Are there any other countries with their military base in a foreign country?
3) Why did India set up its air base in a foreign land? Wont it be interfering with our Non-Interference foreign policy?
4) Also, is this allowed as per UN norms?
