How much of Europe is speaking German right now?
____________________________________________________________
Again, so? And as a practical matter, a lot of people in Europe speak more than one language. Probably due to the fact that travel is easier now, they are closer together, etc.
But my question had to do w/ killing. Is killing the only method to keep freedom?
Can you suggest an alternate method for dealing with the Nazis, the Soviets and Al Qaeda?
Judging by the means to secure freedom (1776), keep it that way (1812), provoked once (WWI) and again (WWII), yes, the best way to maintain peace is to prepare for war. You’ll see that often on here.
