"It's the story of a war through the eyes of a child, but it is also the story of a nation to remembered."

In 1970s was a meaningless war for Cambodia, unconditioned bombing on Cambodian land caused half a million innocent life. Cambodian remembered. What is left until today is nearly 4 millions landmines, most of it still remain uncleared.

There is evidence that during 1969 Lon Nol approached the US military establishment to gauge military support for any action against Sihanouk.

Following the coup, North Vietnam forces invaded Cambodia in 1970 at the request of Khmer Rouge leader Nuon Chea.

These events marked the start of the Cambodian Civil War pitting Lon Nol's regime backed by US air power against the Khmer Rouge and North Vietnam. Lon Nol fled Cambodia in 1975 right before the Khmer Rouge's seizure of power, it was the 'Year Zero.'

17 April 1975.
