Yes, the United States needed to suppress the rebellion at the time of Spanish - American war. This was at a time when colonialism was still popular and failure to take action would have resulted in another power, most likely Imperial Japan, taking the territory by force. It is also important to remember that America was still establishing itself as a great power and needed to project its power further in the Pacific sphere of influence.
American forces should have not tried to suppress rebellion in the Philippines during its push for independence from Spanish and U.S. rule. It would have just started another war that we did not need at the time. I think countries should start to figure out the solutions to their own problems.
The american forces should not have tried suppression on the rebellion in the Philippines. During its push for independence. If this tactic would of been tried, it most likely would of backfired and cost many American troops their life because of the very dangerous conditions they were fighting in. The generals were right.
It is never good to say you rule over anyone period. Granted, those were different times and people thought much differently than they do now. Suppression creates uprisings because everyone likes choosing how they want to live. People do not like being told by outsiders how they should be living their life. They definitely do not like to be held down by other people because those people think they should live like them.
I do not believe American forces should have tried to suppress the rebellion in the Philippines during its push for independence from Spanish and U.S. rule. When a group of people desire independence then everything possible should be done to make sure they receive that independence. I find this to be important for relations down the road.
