Is India under threat from the Chinese?

The Chinese are long since the aggressors where India is concerned. For some time now, China has been eyeing the North-East border state of Arunachal Pradesh and not even issuing visas to Indian tourists from that state of India to its country as it considers the residents of Arunachal Pradesh to be Chinese! India, it seems, is still to wake up from the all too real threat! Even after 146 incursions in 2006! Isnt that strange!
