That's right I'm back with another scenario (sorry for taking so long I ran out of inspiration).

On December the 17th 1961, India marched a garrison of troops into Portuguese controlled Goa and annexed it, claiming it was Indian land stolen from it. The annexation took 2 days and on the 19th Goa was Indian.

Portugal, as expected, was utterly furious and tried it's best to retake it. It argued that Goa was not a colony but an actual part of Portugal despite being 2 continents away. It gave this excuse to NATO hoping for help (Article 5 {attack on 1 NATO nation is an attack on all}). However NATO did not buy the excuse and Portugal eventually dropped the subject.

However what if NATO agreed to Portugal's claims and Portugal actually used Article 5, today we will explore 2 scenarios, one in which NATO invades and defeats India and another in which the USSR intervenes and a 3rd world war starts.

Let's start with the first scenario.

The date is 1st January 1962 and Prime Minister (ahem dictator ahem) Antonio de Oliveira Salazar declares that after carefully considering the options he has decided to invoke NATO article 5. He stated "Portugal has already been pushed out of Africa by it's rebellious colonies, we will not lose lose a vital part of our country whether it is considered a colony by India or not. Therefore we invoke article 5, hoping our allies see the injustice done to us by the Indians!".

2 days later the secretary general of NATO recognizes the use of Article 5 by Portugal and calls upon NATO nations to help their fellow ally.

This would lead to the parties of the different NATO nations to meet up on 10th January to discuss the situation. One thing would lead to another and NATO would prepare for war against India.

The Indian reaction to this is be one of shock and dismay. The Prime Minister, Pandit Nehru gives a statement to his country "My fellow people, the reaction of the world to us retaking our former land is of anger and rage. We face a threat far greater then when the British threatened to colonize us all those centuries back. But I implore you to remain steadfast for we and our allies will lead India to victory!"

Following the speech Nehru and Salazar would meet in Vienna, Austria to discuss the invocation of Article 5. Salazar would give Nehru the option of returning Goa or war against NATO. Nehru refuses to return what's rightfully theirs and so preparations for war begin.

NATO began to make a plan which took 2 weeks as the different leaders of the nations would meet up and discuss strategy. Finally, a plan would be made, it went as follows

NATO forces consisting of 2000 men from France, 3,900 from Germany, 3000 from the British, 930 from the Spanish, 1670 from the Italians, 300 from the greek, 0 from Iceland (only history fans will get this joke), 400 from Norway, 3500 from Turkey, 1500 from Canada, 2800 from Denmark and a whopping 5000 from the US, making a total of 25,000 troops would land in Rawalpindi, Pakistan on the 2nd of February 1962, Pakistan was a close ally of the Americans and west at this time and a huge rival of India and would hopefully help in the invasion.

From there troops would enter Lahore and cross the border into Amritsar, from there the troops would divide with 15000 marching straight to New Delhi and another 10000 marching on to Goa, hopefully destroying industries along the way, Once New Delhi was under NATO control the rest of India would fall and the war would be won.

They reached out to Pakistan and President Ayub Khan would gladly agree to assist Pakistan's fellow allies, under the condition that Pakistan got Indian-controlled Punjabi, Kashmir, Rajasthan, Gujarat, Rajkot and Ahmedabad. NATO agreed and the plans were set into motion.

Over in India, Prime Minister Nehru would most likely be preparing his troops for war as well, India at the time had armed forces of about 550,000. They outnumbered the NATO army that was being sent however were not as highly advanced. Nehru, fearing the worst, would prepare an army of 250,000 men and would place 20,000 at Goa, 50,000 at New Delhi and the rest along the Pako-Indian border. Nehru also met up with current Soviet President Nikita Krushchev on 28th January to ask for a military alliance. Krushchev would declare full economic support of the communist world to India but would refrain from supporting them militarily, 1 thing is to be noted that China did not support India and sanctioned it, declaring that Portugal had every right to retake Goa. 

on 2nd of February 25,000 troops would land in Rawalpindi via aircrafts and from there they would reach Lahore by noon. There they would camp for the entire day and finally on the morning of the 3rd of February 1962, enter India. they would meet an army of 2000 at the border and easily defeat them with minimal casualties. despite India's large numbers. Nato's well orginized and highly advanced troops steamrolled through India until they reached Amritsar. The Siege of Amritsar would last 3 months and finally on 6th May, after a reinforcements of 40,000 Pakistani personnel and 32,000 more Nato troops (bringing the army upto 95000 (with 2000 already dead on their side). from there there 60,000 troops would march to New Delhi and 35000 would march to Goa.

However India would not completely face losses, as soon as news of Pakistan's involvement in the fall of Amritsar would reach Nehru, he would order a corps of 66,000 men (divided into 4 divisions) to march into Pakistan via Sindh. The army would first battle a small undertrained army of 500 Pakistani soldiers before marching onwards through Hyderabad and laying siege to Karachi, however the siege would continue for the rest of the war as a combined navy of 3000 ships of NATO and Pakistan would be defending the city and supplying it with reinforcements and supplies. However an army of 4000 would march into Pakistan controlled Kashmir and capture it, followed by slowly marching the province of Khyber Pakthunkhwa and destroying the local economy, on their way to Islamabad. 

Back in India the 60,000 strong army would reach the outskirts of New Delhi and lay siege to the city, however again due to strong preparations the Siege would last for the next 5 months. the second army of 35,000 men would also face difficulties as they would reach an empty Mumbai and occupy it, only to be surrounded by an Indian army of 40,000 men and 40 Naval ships. The army would find itself under siege and trapped.

After 5 months, NATO and India are still at war and are at an impasse with neither able to defeat the other, however that would change on 20th October 1962 when China would march 3000 men into northern Indian controlled Kashmir and modern day Arnachal Pradesh wanting to use the war to its advantage and retake its lands as well. This surprise attack would lead to minor resistance and China would take all of Assam and Nagaland in the east and all of the Northern mountainous regions of Kashmir before stopping.

This surprise attack would further divide China and the USSR as the USSR was a great ally of India, the 2 major communist nations had already ended relations on 18th July of the same year and now the USSR was a few steps away from war with China [don't worry I'll make a what if on this as well :)]

 At the same time a US led army of 40,000 would land at Goa capturing the city and heading to Mumbai to free the 2nd division (which now had 20,000 men left). India, facing a war on 5 fronts would finally surrender on the 1st of November 1962. The casualties of the war would be 45,000 Indians dead (5000 of them being civilians), 10,000 soldiers from NATO, 35,000 Pakistani casualties (3000 being civilian) and 400 Chinese casualties.

Nehru and the leaders of NATO, President Ayub Khan and President Liu Shaoqi of the PRC met in (again) Vienna to discuss the new treaty, It would be as followed:

Portugal would be given Goa and the entire province of Karnataka as reparations of the war, China would keep Assam and Northern Kashmir but let go of the rest. Pakistan would gain Indian Punjab, the rest of Kashmir, West Bengal (including Calcutta), Nagaland, Rajasthan, Rajkot, Ahmedabad and for their further support and losses in KPK, Chandigarh and Uttarkhand. India was to reduce its army to 250,000 men and for the next 20 years never let it increase above that number, they would also be paying each NATO member 50,000 Indian Rupees per month for the next decade, paying Pakistan 75,000 Indian rupees for the next 5 years and paying Porugal a total of 3,000,000 Indian rupees within a year. China would have to pay India 400,000 Chinese Yuan for taking more then what they said they wanted.

This would result in several things, for one the world would see how effective Nato is and the USSR would be more careful against it in the future, China also revealed its ruthlessness and other nations were quick to ally with the new world power. Pakistan grew considerably more powerful and after creating a defencive pact with China in 1964, both nations created the Asian version of Nato which would considerably boost their power. Pakistan would also manage to keep hold of Bangladesh and it wouldnt get its independence until 1992.

Part 2 will be written and posted soon where the other scenario will be talked about, so stay tuned!

Well there you have it. I hope you enjoyed reading and be sure leave your suggestions for any other ending which could have happened down in the comments!  And if you want to give me a suggestion for an Alt history event feel, free to ask in the news section of my profile page! Anyways thanks again, Good day and Good bye! (also I work really hard and research a lot for these Alt history scenarios so a vote would be extremely generous of you, although it's entirely upto you).
