You mean American Troops? Because I can assure you the fascist US regime continuously kills and abuses its own citizens. They have destroyed millions of minority and poor families with the War on Drugs and terrorized tens of millions of civilians with police violence. They have lost more citizens to gun violence in the last thirty years than every US soldier that has died in every conflict since the creation of the US. They allow the wealthy to murder, rape, and steal from the populace with impunity. They still are engaged in multiple ongoing genocides with their own people.
