Thank christ for the bomb

In 1914 a war began, a million soldiers lent a hand,
Weren't many planes to give support, hand to hand was the way they fought.

Young men were called up for the cause, for king and country and the cross,
In their naivete they thought it was for glory, so they'd been taught.

In 1939 once again there came the sound of marching men,
Occupying European land, all the way to North French sands,

But, in the final year of that war, two big bangs settled the score,
Against Japan, who'd joined the fight, the rising sun didn't look so bright.

Since that day it's been stalemate, everyone's scared to obliterate,
So it seems for peace we can thank the bomb, so I say thank Christ for the bomb (3)
