Uncovering the myths and hidden truth under Pulwama attack

The act of pinching kashmiris and promoting brutality has deepen its roots in Kashmir. Regardless of the fact that kashmir was illegally occupied by India, Pakistan wants a peaceful solution of kashmir issue with India. Then what's the hidden truth behind Pulwama attack? Like Mumbai attack was Pulwama attack carried out by India?

1. Incident happened 150 KM deep inside the valley on a military convoy of 2500 strong soldiers.
2. Preparation of such vehicle borne IED takes months. How in military saturated IOK, it got prepared for so long where there is one soldier to every 7 Kashmiris?
3. How only one Suicide Bomber that too local can do this? 
4. It needs expertise. Leave behind all incidents of oppression. How it’s possible that such a huge quantity of explosive reached there undetected?
5. It was a planned but not an abrupt move of over 2500 troops for which route was secured?
6. JeM and Lashkare Tayyaba are synonymous to freedom struggle in IOK and In the times of fake news making videos with banners of any militant outfit is possible. 
7. JeM has denounced owning the incident as being claimed across by Indians.
8. All responses on blast are coming from non-Kashmiri political leadership, Why No media response from Kashmiri leaders and routinely victimized common man from IOK?  
9. Their narrative of isolating Pakistan was fast getting defeated hence yet another False-Flag operation was in the offing to resurface this narrative? 
10. Important for Indian to defeat Pakistan’s effort of making Afghan Taliban agree to regional peace not only in Afghanistan for which Pakistan was blamed. Hence important for India to shift Goal-Post, present to the world that Pakistan seeks space to create such proxies?
11. Kartarpur initiative had been a big defeat for India in which Sikhs all over the world and especially in Punjab appreciated Pak. Is this not the dirty Indian move to spoil 550th birthday celebrations of Guru Nanak in Nov 2019? Indian had to scuttle it through such tactics.
12.  India had reluctantly agreed to permit visit of Indus Water Treaty Team in IOK after a lapse of 4 years in January this year. India never wanted this process to mature for future, hence created an event to dodge it out for future?
13. The Leading Q arises, Who is the beneficiary of such incident especially from timings point of view? Pakistan who has peacefully check-mated India on Diplomatic, Strategic, Economic and International forums can afford this?
