If "Migrants" flooding the US border are fleeing their country in fear for their lives, why are they flying THEIR country's flag and NOT the USA Flag?

Why are the breaking into the USA claiming that they are fleeing an evil county, and then waving the flags of the very country they claim to be in fear of (including COMMUNIST COUNTRIES) instead of the American Flag in celebration of their respect for OUR country and appreciation of our generosity (other countries would have shot them on sight).

This is NOT a mercy mission. IT IS AN INVASION.

WE NEED A DECLARATION OF WAR AND US MILITARY TROOPS ON THE MEXICAN BORDER TO STOP THE DEMOCRAT'S ILLEGAL INVASION AND PROTECT THIS COUNTRY!
