Some of the neighbouring countries of India are jealous of India's developments in recent times. So they have kept no stones unturned to hinder the progress India is making in various fields. Many have captured some regions of India, infiltrated their men in these captured regions of India and set up terrorist outfits to create disturbances in India to hinder our progress.
Pakistan has occupied almost more than half of Kashmir in its north (Pakistan-occupied-Kashmir) and maliciously named it Azad Kashmir. Thus they call the Indian part of Kashmir as India-occupied-Kashmir which is not actually true. Kashmir has always been an integral part of India just the way Alaska has always been an integral part of USA. China has also captured the north eastern parts of Kashmir, named it Aksai Chin and created their national highway to make their soldiers come to India and fight with the Indian Army without any difficulty. China has also captured many parts of Uttar Pradesh and Himachal Pradesh. China has been instrumental in capturing Tibet and now they have marched towards Indian state of Arunachal Pradesh in the north east and claim this state to be their territory.
Any tamper to the Great Wall of India by any of our neighbours from their side can be put forward by India on the world court and can be questioned in the most severe of terms. Thus India can ward of any future borders disputes created by her neighbours by building this permanent structure. Thus no other neighbouring country can ever claim the sacred Indian soil to be their land.
If such a bold step is not taken from Indian part, I am afraid China might eat up all the north eastern states like Assam, Nagaland, Tripura, Meghalaya, Sikkim, and even claim the communist Bengal to be their part. In the similar way, Pakistan might claim Rajasthan, Gujarat, Haryana, Punjab and march off to Madhya Pradesh, Maharashtra or even Delhi. Capturing Delhi means capturing the whole of India.
So along with spending crores in warfare, India should also spend only a few crores in building a permanent boundary which is the Great Wall of India.
NOTE: - I will design such a boundary in some of my later post and describe it accordingly.
