Though the initial evolving of India during the early years was totally socialist in nature and not to my pleasure, still despite this one drawback and a lack of strong sincere leadership India trudged ahead. Pakistan's obsession with religion in everything; from social life, to politics, to schooling, to relationships caused it to eventually start cracking. Having no individual cultural and ethnic heritage, Pakistani leaders went ahead making that country into the "living breathing Islam". This single-point strategy envisioned a Pakistan that re-united the old Ottoman Empire, this time having a base in South Asia.
Due to limited vision and understanding of modern politics and having selective myopia on their outward perspectives, Pakistani leaders started viewing the world in their own image; meaning that a country could exist for them only if it had an indigenous religion and if it didn't have, it didn't have an credibility to exist as a nation. This self-ignoring and lack of a distinct cultural identity and their obsession with making themselves based on Islam, made them forget that other Muslim countries relied not just on religion but on distinct cultural habits. TO the extent that the country that Pakistan idolized, modern Turkey has an interpretation of pre-Islamic Turkic religions that were existing in tribes and blended them with Arabia's Islam, creating a distinct, modern and more tolerant version of religion that made them focus on more practical aspects of running a country; economics, politics, education, scientific development, engineering, infrastructure, national defence and so on.
By 60s and 70s, Pakistan became so obsessed with Islam that everything was seen even more a requirement for everything. Soldiers were encouraged on adapting to hardline interpretations of Islam and indoctrinate themselves on the lines of "Ghazis" or "destroyers of Kuffar". Another theory that becomes the false foundation of this mentality was that of the "martial race" concept that the British used during their time in the sub-continent to favour a specific bunch of people as "superior to others". Since Pakistan's foundation was to deny everything that was Dharmic (Indian by origin) whether ancestral or cultural, religion or customs in society, they further lost themselves in this vortex of superiority complex with General Ayub Khan's famous line "1 Pakistani = 10 Indians".
This dangerously narrow-minded and intolerant mentality was further fueled by radical air giving countries like Saudi Arabia who's own regressive and intolerant interpretation of religio-political philosophy egged Pakistan into becoming more Arabic than Arabs themselves, more Persians than Persians and more Turkish than Turks themselves. All this while their inability to demographically put Kashmir in favour of "land of Muslims" failed in 2 wars, one of which caused their existing territory to be torn into another country (1971). During 80s, numerous failures in the form of small skirmishes successfully thwarted by Indian Army fueled religious fanaticism to new levels when Pakistan finally resorted to using of religiously fundamentalist Islamists from Soviet war into Kashmir; this horde of zealots entering into the valley made sure that the existing Muslims of Kashmir were radicalized enough to start their conquest of the state through ethnic massacre. In total, it is estimated that more than a lakh non-Muslim Kashmiris mostly being Hindu/Sikh or Buddhists were killed, raped, manhandled, attacked, threatened and arond another 5-6 lakhs were driven out with sheer violence.
This showed the beginning of a non-military religion-themed war that a desperate and frustrated Pakistan resorted to due to their inability to take Kashmir by simple military force. While Indian government fumbled with the Soviet collapse, it was careless not to ensure safety of pandit, sikh and buddhist community with their safe return to the valley and therefore couldn't stop the islamization of the valley that radicalized the otherwise peaceful people of Kashmir.
All this while Pakistan's downfall had already started taking place. With the US disenchantment of Pakistan post Cold war, the former stopped and sanctioned all of military aid supplies that Pakistani armed forces were being blessed with for the past 4 decades without having to pay much for it, on the grounds of CIA realizing Pakistani nuclear ambition. Leaving the job of creating problems for Indian forces in Kashmir to Islamic radicals in the valley, Pakistani army was free to pursue politics like never before. However, in their elation of being able to attempt to "bleed India with a thousand cuts", little did they realize that the gamble of religious terrorism that they had started carried a very horrific dark side; a demon so fierce that their poorly managed, madrassa influenced country would not be able to manage.
The demon started showing itself more and more by the time the nationalist NDA government came into power in India, furthering the economic liberalization that Dr. Manmohan Singh had initiated in early 90s post Soviet collapse. The arrival of more assertive and fierce nationalist regime in India saw numerous occasions of tension with Pakistan especially after PM Vajpayee's declaration of India as a nuclear weapons state. Unkown to Indian officials then was that China had already embarked on supporting its only military puppet in Asia, namely Pakistan with nuclear weapons technology and according to some reports had tested nuclear bombs for them in Chinese territory itself, therefore making Pakistan appear successful just merely 3 weeks later as a nuclear weapons state. The demon of Pakistan's jihad began to show signs of pressure when the then PM Vajpayee attempted to dissolve the tensions and enmity with a historic state visit to Pakistan. However unbeknownst to the then Pakistani PM, his more aggressive and Islamist motivated generals had already embarked on a plan to once again try to take Kashmir by force; an act which initiated the Kargil conflict in 1999.
This last attempt to take Kashmir by force also as its previous attempts saw a crushing defeat. Despite flattening Pakistani backed terrorists and undercover military officers, the war exposed numerous weaknesses of Indian armed forces, catching the government cold feet, which embarked then on a rapid modernization and upgradation programme of all weapon systems in the tri-services in India. Due to the absence of India's largest partner and longtime friend, the Soviet Union, the nationalist NDA government began to expand ties with alternate countries like Israel and France, who increased their arms supply and were the only 2 countries apart from Russia herself who refused to condemn Indian nuclear tests and openly supported the Indian cause in front of the world. Relationship with the Jewish state of Israel reached all time high under the NDA regime when Israel send emergency supplies to Indian army of 155 mm shells during Kargil war without questioning. Looking at Israel as a stop gap supplier and alternate line of military diplomacy, NDA embarked on a shopping spree for cutting edge systems for Indian military's modernization, all this cemented with the first state visit of Israeli PM Ariel Sharon.
This visit sent shockwaves in Pakistan's elite ruling group for Israel was the only other country that Pakistan had nurtured its ideological hatred against due to their obsession with Islam and Arabophilia. Pakistan's religious zealot Army once again saw disappointment in personal terms as it struggled with explaining its public about the war, ultimately refusing accept their own deceased soldiers to censor the news of their defeat to local public: a historic policy of Pakistan's military throughout its conflict period with India since their inception in 40s. Another factor that changed the dimensions of this two-nation conflict was that post-1999 for the first time in more than 55 years, India was able to expose Pakistan's hand in terrorism in Kashmir to the entire world. The nuclear testing, the war victory and the diplomatic victory in exposing Pakistani hand of terror boosted the rating of the ruling NDA government in India, costing Pakistan the deafness that US had maintained for so many years about their hand in terror.
The demon become even worse when 9/11 tragedy struck United States and opened world's eyes to a new enemy for the first time after collapse of Soviet Union; Jihadic terrorism. Due to Pakistan's significant hand in radicalizing mujahideen to fight USSR, this time Pakistan was caught on the receiving end when Bush administration issued an ultimatum; "either you're with us or against us".
After that.... we all know the story.
