Answer:
Reasons in favor of U.S. involvement in the Boxer Rebellion:
1.- The Boxers attacked United States Citizens
2.- United States citizens' interests were in risk
Reasons against U.S. involvement in the Boxer Rebellion:
1.- United States' citizens that had not been attacked could have been targeted because of the intervention.
2.- The interests of the United States Citizens that hadn't been damaged could be compromised.
Step-by-step explanation:
First of all, the Boxers attacked foreigners including United States citizens based on racism. Second, many of the United States citizens' interests in China were compromised already, so the United States government had to support them. However, that could compromise citizens' and citizen's interests in China that had not been compromised already.
