After their separation in 1947, relations between India and Pakistan were in an almost constant state of excitement. Both sides have fought several major wars – most recently in 1999 – with thousands of casualties and numerous battles across the control line in the disputed Kashmir region.
Since this last clash, both countries have been pressing for expansion and improving their military capabilities.
With its military buildup over these decades, India now surpasses Pakistan in most numerical measurements – fighter jets, troops, tanks, and helicopters.
India surpasses Pakistan in other measures, especially in the military budget, with $ 64 billion According to the International Peace Research Institute in Stockholm (SIPRI) to 1
But as is often the case, numbers do not tell the whole story.
The China Question
According to the International Institute for Strategic Studies, India has about 3 million military personnel compared to less than one million in Pakistan, but New Delhi can not focus on its western neighbors.
One piece focuses on northeastern India and its border with China.
"India's strategic problem brings its strength to bear, traditionally it had to divide its forces and leave some in the East to discourage Chinese adventurism." Peter Layton, a former officer of the Australian Air Force and now a fellow at the Griffith Asia Institute.
And China is able to separate Indian attentions through a close military relationship with Pakistan.
"There is a convergence with China's and Pakistan's strategic thinking that has been going on for five decades," said Nishank Motwani. A guest lecturer at the Asia-Pacific College of Diplomacy with expertise in India and Pakistan.
China plays a different role than Pakistan's largest arms supplier – with 40% of Beijing's military exports to Islamabad December discussion of Pakistan at the Brookings Institution in Washington.
India's Relations with the West
While Pakistan has established a close relationship with China, India has implemented its own rapid military modernization program, with a defense budget six times that of Pakistan.  "India has more purchasing power and is investing in platforms that Pakistan can not afford," said Motwani.

deployed along the Kashmiri line as a replacement for the Swedish guns of the 1980s However, new military technology is often hampered by strict export controls by key suppliers such as the US and the UK.
Other experts say India is also injured by a poor indigenous military industrial station.
"India does not have an ecosystem of industry, so they have no design experience, they may have intelligent engineers, but that does not mean they can design a fighter jet," said Manoj Joshi, a Fellow at the Observer Research Foundation in New Delhi.
Pakistan is now producing its own combat aircraft, the China-designed JF-17.
According to some reports, it was one of those jets who shot down an Indian Air Force fighter Wednesday that led to the capture of an Indian pilot by Pakistan.
This Indian jet was a MiG-21. A Soviet-designed aircraft has been in service since the 1960s, and the Indian Air Force still says that it "makes up the backbone" of their fleet with about 200 in stock.
But Motwani says Indian pilots call the old jet "the flying coffin" for the accidents in which it was involved.
