Security is at the heart of India's foreign policy. S. Jaishankar points this out at Thiruvanathapuram. He says this was true of the effort at Balakot and even in the midst of Covid at the Line of Actual Control with China when India sent up enormous numbers of troops to defend the border. This is also behind the stand with China that security and LAC comes first in all relations with China. Trade and exchanges all come in the context of LAC, settle the LAC issues first then we can proceed with better bilateral relations, this is what India is telling China. There are good reasons for this. India has a large border in the most formidable terrain of the Himalayas which is also close to the plains of India in the LAC with China. Any difficulties at the border would weaken India's secuerity and weaken development efforts in the same way that Japan sought to weaken Chinese development through invasion in the 1930's. Tibet looms out of the past. When China invaded Tibet Nehru's couple of pages in Discovery of India on China show that he had no idea of the China that had emerged with Mao and the CCP in its historical struggle against Japanese nationalists and imperialists. He had an idea of China that came from the Buddhist period and India's links from the past. The ruthless Japanese invasion that China confronted on its soil, and British colonial incursions before that, had already transformed the China of the past, which now under Mao in 1948 may have sought more defensible borders by extending them to Tibet as a buffer state. Historically the British had never tolerated Russian or other European or Japanese interference in the border states such as Tibet. There was also the question of capacity. By the time of the invasion of Tibet in the early 1950's China had already fought the Korean War with the US. India's army and defense forces were just coming out of partition and ill equipped for the task of defending the borders in Tibet region. Current governments in a more normal setting cannot change this part of history, yet can take full recognition of the facts that this has created. A strong defense has to be created for defending a border that extends for thousand of miles now that China has unlawfully occupied Tibet. On it also depends a strong and vigorous development effort that helps build the kind of modern defenses as the economy grows and absorbs new technologies rapidly. Both defense and development go together, one cannot have defense without rapid modernization and development, and one cannot have rapid modernization and development without defense. A weak defense would lead to distractions in development leading to the lack of rapid modernization and development as the intruding power interferes in insidious ways in the internal and external links of the country. This is the lesson of colonial interference of western powers in Asia. As Brendan Simms shows in his new book, Europe - Struggle for Supremacy 1500 to the Present, it is also the lesson of a different kind of colonialism inside Europe since 1500, where weaker states inside Europe fell behind with interference in turns by the imperial powers of France, UK, Austria-Hungary, Prussia and Russia. Poland, Finland, Czech Republic in the past and even Ukraine today are just some examples of what can happen when one loses sight of this principle. Poland and the Polish Commonwealth in the 19th century, Hungary right down to 1956, and China in the 1910-1930, India in the 18th and 19th century were weakened internally even after recognizing the problem, so that recognition of the problem is not an adequate condition to prevent countries from facing such foreign interference. ...
