Iran moves to legalize marriage for girls under 10 years old
Over 40,000 Girls under Age 15 Married Each Year in Iran.
In 2012 there were four births by girls under the age of 10, 17 births by girls under the age of 11, 50 births by girls under the age of 12, 275 births by girls under the age of 13, 1,289 births by girls under the age of 14, 4,377 births by girls under the age of 15.
These CHILDREN are not even fully developed yet.
Neither mentally or physically.
Might take them a couple of generations to acclimate to Poland's civilized culture.
