1) unwanted
carpetbaggers were viewed as traitors by the south, so they were unwanted
Manifest destiny said that people with money and a higher power (such as the big companies at the time, oil, steel, etc.) were more superior than the inferior African American slaves. The north did not believe in manifest destiny, but the south wanted to keep their slaves and the tear began.
The quote means that you should speak cautious and nonviolent but be willing to use violent when things go south, the big stick is like an unsaid threat. Therefor the answer is 2 because when he intervened in the affairs he hadn't been hostile like other leaders of other countries, but they knew of the military power the US had, and was willing to use.
Hope it Helps :)
