The main export of the Minoan civilization, which was based on the island of Crete, were their achievements in pottery, cutlery, or rather culture and art in general. The Minoans were renowned for their capabilities in creating painted pottery which was also a product that they exported outside of the borders of their civilization.
A peasant is a low income and low notability who owns or rents a small piece of land for cultivation (chiefly in historical use or with reference to subsistence farming in poorer countries).
Most people didn't support the war, so you can sing in the POV of an American hippie, soldier, Vietnamese soldier, citizen, or government official. According to many websites, folk music started the spark of protest against the war. This means that maybe you can sing in a folk song theme. The war was long and brutal, which is why I would not support the war. You could divide it into 5 stanzas with 4 lines each.
One stanza could be:
Life in Vietnam is hard for me,
When I wake up I hear M16's,
When the bombs rain down I know things are changing,
This skirmish is rapidly raging,
Hope it's not cringe :)
