We’ve had “Deutschamerikaner” for two world wars, just like we have had people descended from other nations whose countries of origin have been our enemy during those wars. Deutschamerikaner in large numbers even date back to Benjamin Franklin’s time; the man once thought that Pennsylvania was going to consist of a German-speaking majority, hence his creation of the Philadelphische Zeitung at one time. Obviously I was not talking about them.
BTW, citing Wikipedia will get one into trouble, never mind the US Census Bureau (who has been responsible for the redistricting that pushed conservatives out of the House and Senate).
You are obviously in denial. LoL!
1608 - Several Germans were among the settlers at Jamestown.
