I believe the flag should stay up because that memorializes the Civil War and the whole receding from the U.S.
That would be 4 Japan, where they dropped the two nuclear bombs in Nagasaki and Hiroshima
There were lots of foreign changes that presented challenges for the US. I'll give you a few examples from different time periods. First would be when England wanted to tax the Americans in the Revolutionary period. They did this to try and restrict America's freedom. Another example would be that Russia had spies during the cold war period. This was to gain intelligence of the US war plans. Also when Germany sent the Zimmerman Telegram to Mexico during the WWII period. This was to get Mexico to launch a surprise attack on the US.
In total, the Black Death has killed about 450 million down to 350-370 million in the 14th century.
Hope that helped! :)
