personnel lost their lives in the Galwan valley in Ladakh. We will not let the sacrifices of our brave soldiers
go in vain. The entire country is standing firmly behind its armed forces," Rawat said.
"Our enemies should know that in 1971, India had heralded the birth of a new nation on the map of the world. In 1965 and 1999, Indian forces had driven away Pakistan from its territory. They should know that India will take back every inch of its territory from China," he added.
