Are we prepared for another war??? or being Realist?

In history of World politics and international relations, in between the First World War and the Second War the world politics were divided into two, the realist and the ideologist. Not many would recall so I explain Realist are those political groups who gives high priority to their nation and believe in attack, just like the approach of earlier British and Nazi's and Ideologist were followed by the Great Lenin of USSR, Mahatma Gandhi and many.........After the Second World War the World went into Cold War and someway adopted the Ideologist way.
Now reality check from the eyes of an Indian...
the world is still divided and in Cold War with the fear that now almost every Nation States has reached its highest security level and no State can think of WAR. INDIA is following its Ideologist strategy within country and in its foreign policy but surrounded by the Realist States. What it shows that after Tibbat China is now showing its authority on earlier on Sikkim and now Arunachal Pradesh? Its proved that China is not with India when only the China denied the loan to India during UN summit. One side it's Pakistan want to take Kashmir and on other side it's China for Arunachal Pradesh. There is a method in the boorishness displayed by the Chinese in protesting against the visit of Prime Minister Manmohan Singh to Arunachal Pradesh and India rectified his failure to visit the monastery town of Twang by sending Defense Minister A K Antony to supervise investigations into the desecration of Buddhistt relics there, thereby reasserting Indian control in the border State.
Why should not Media covering this fact and Chinese infiltrations into India's border and why not Government showing its stand on it? Once again Siechan fight once again Kargil War once again our soldiers are scape goats and besides praying we can't do anything. Is this justified? Or we should also turned to Realist attitude???
