As I have stated on numerous occasions, in international relations, bilateral and multilateral relationship develops on give & take basis. Unilateral friendship is not possible, even if it is possible, it does not continue for long-term. Same is happening in respect of SAARC. It is not permanently possible for India to go on helping the neighbouring nations without getting much in near and distant future. Moreover, helping those countries create various controversies. The attentive readers off newspapers can remember the unnecessary controversy about the proposed Rampal thermal power plant in Bangladesh. When India tried to help Bangladesh unilaterally, the opposition parties of Bangladesh (BNP, Jamat and Jatiyo Party) created tremendous hue and cry against the proposed project of NTPC to help Bangladesh.
Moreover, these countries won't help India to get permanent seat of UNSC. They can't help India to become a super-power, either military or economic.
So, SAARC may be allowed to die peacefully. We will write good obituary after its death.
(This is my personal opinion.)
Beware! I question everything and everybody.
