If India and Pakistan went into another all-out war, Pakistan would be victorious.

To start:Argument I: Pakistan v India Economy.Pakistan is in no position to challenge India. Pakistan has among one of the world's smallest Economies per capita, at $884.2 bn, or $4515 per capita (1). This is under India's $7.2 trillion and $5,777 per capita (2). The difference in per capita doesn't seem large, but it's a 22% gap. Per capitas are important, but so is absolute value. India can draw in more tax revenue per capita, as well as (assuming they draw the small percent of the economy for war) 8x the total amount for war. India is the world's third largest economy. Economically, Pakistan is doomed.Historically, Pakistan has a track record of massive loss. In the four wars prior, they lost the first, and suffered far higher losses afterwards. Each war was worse than the prior for Pakistan. The downward cycle implies future loss. The downwards cycle continued in the Kargil War, will Pakistan claims less loses, but other sources claimed losses as high as 7x that of Indian loses. Had it been one war, it'd be reasonable to claim Pakistan might win, but after 4 losses, each worse than the last, the resolution is highly improbable. Especially since India's economy is growing at a rate of 2.1% higher than Pakistan (150% faster than Pakistan)(3, 4). And India's inflation rate is half of Pakistan. The rate of which Pakistan's inflation increases nearly blocks out economic growth. India's rate of economic growth grew 13% since 2014, while Pakistan's economic growth grew by only 3%. Pakistan stands no chance alone.[1] http://en.wikipedia.org...[2] http://en.wikipedia.org...[3] http://www.adb.org...[4] http://www.adb.org...[]Argument II: Pakistan v India Military.According to the Global Firepower website, India's the world's fourth strongest Military. Pakistan isn't even in the top 10. Global Firepower ranks Pakistan at 17th place (5). Pakistan's Reserve and Active forces in smaller than India's Active forces alone (6, 7). When Reserve Forces are included, India has three times the army size. This, with the fact that India spends almost $11,000 per soldier, compared to Pakistan's $6,180 (8). India also maintains first world tanks, compared to lower quality Pakistani tanks. India has 2x the number of tanks.India far surpasses Pakistan in every way. Especially since Pakistan has a major terrorist infection, primarily the Taliban (9). The domestic issue would cripple any Pakistani war efforts with a power like India.[5] http://tinyurl.com...[6] http://tinyurl.com...[7] http://tinyurl.com...[8] http://tinyurl.com...[]Rebuttal I: China.Pro believes that China will enter the war. This is entirely false. Pro himself stated that Chinese-Pakistani relations were strong for over sixty years. This puts the start of their close relationship around 1950. However, there have been three wars between India and Pakistan (one as recent as 1999,) and China has never gotten involved. This despite every argument Pro made. All of his arguments stood back then too, and yet China stayed out.China has no allies. They maintain a neutrality policy. They have no intentions of going to war, especially against India. India is right behind them militarily, and has a massive draft-able population and financial powers. Pro stated this earlier, showing them compared to each other. What Pro forgets is modern politics... War between the two would catastrophic. They are too close in power for China to declare war. It's not as simple as showing China's military being stronger...Assume, though, that China gets involved. China is only the third strongest power. Russia surpasses China in power (5, 10). China maintains a no-alliance policy, despite their close ties with Pakistan. However, Russia and India are entirely allied. They provide strong economic and militaristic aid, and their alliance is only getting stronger (11). China would be against the second and fourth strongest armies in the world. That being said, it's not beyond Russia to aid India in the event that India is losing, but it is unlikely that China would aid Pakistan against a force like India.To counter this right away: Debt is not a reason for the US to stay out. Federal Debt runs off a Bond system. China owns US bonds, which can not be called upon until they have matured. Even if they could call on them earlier, it'd be economic stupidity. Federal debt is a loan... It's a purchase. China could own 100% of the US Debt, and yet not be able to call on it. Although the US actually pays it off via interest each year, and that's what the bond is worth... That interest collected. So if they did call on the debt, we'd already have the money for them. Even than, China only owns 8% of the Debt (12). In reality, buying US bonds is good for China, so they would want to maintain safe relations with the US (13). If anything, while China can not call on it's debts, the US can cancel all debts to China if they declare war, called Sovereign Default.Pro stated in comments that the US companies would crash if they lost the ability to trade with China. This isn't true. They would simply find resources elsewhere, like India. If anything, China would want to keep relations with US business more so than vice versa. Without US Business, China would collapse under the losses.China would avoid entering the war with the US because relations with the US are stronger than relations with Pakistan, if only because China needs the US. The relationship with the US is far stronger because of dependency on US industry, consumerism, and aid. If Pakistan invaded India, the US would side with the Defender and be at odds with China. As shown, debt and such wouldn't stop the US. Meanwhile, China and Pakistan would be at potential war with the Strongest, Second Strongest, and Fourth Stronger military powers in the world. They would stand no chance.If the US and China ended up at war, this would be the stats between them.China:Spending per soldier: $31,000Tanks: 13,900 (low-grade tanks)Aircraft: 2,800Navy: 673 (1 carrier / mostly low class war vessals)US: (14)Spending per soldier: $230,800Tanks: 99,000 (high-grade tanks)Aircraft: 13,800Navy: 473 (20 carriers / all high-grade war vessals)BUT: That is a severe outcome, and would prevent China or the US from in engaging in war. No matter what combination of super powers you have, the potential outcome would prevent war from moving beyond India and Pakistan.

Only the first one ended with a nation winning. In reality, the war would be stopped by the UN. That, or if Pakistan used WMD's, as Pro brought up them having WMD's as an advantage, the UN would sanction Pakistan until Pakistan stopped existing, or admitted defeat.Although if the UN didn't step in, and China and the US didn't force them to cooperate better, Pakistan would have no odds of winning. The amount of border space to be gained stopped being worth the potential cost of war against a super power long ago. China would never engage India. Especially if the number Pro were listing (hundreds of millions of potential soldiers) a possibility.Pro also mentioned Tibet... China and Tibet have been working out their issues diplomatically... Declaring war would cause Tibet to become a major issue for China. Pro says Tibet is why China would want to get involved. In reality, a troublesome province would pose a throat to Chinese war efforts.Conclusion: China would NOT get involved. If they did, they'd be outnumbered by Russia, India, and the US. The UN would intervene and stop the war. Outside of that, Pakistan poses no threat to India.
