It's not an oversimplification.
The US doesn't do peacekeeping, There isn't a single war in the past 20 years we've been involved in I can call a peacemaking operation besides Afghanistan or the war with ISIS and in both cases not only have our actions failed to create lasting peace but our government has been directly responsible for funding and creating the enemy armies to begin with.
"Disaster relief and humanitarian aid work" this is a virtue signal argument. If America was actually directing it's economic and industrial base towards solving the worlds problems things would not be anywhere near as bad as they are in a lot of countries. Actions speak louder than words, and I see way more bombs than doctors, even the doctors almost always come with guns.
Why do peacemakers need the largest military backing them? We have the peace corp and americorp for genuine peacemaking, both of which are critically underfunded. If America's military actions were genuinely for disaster relief or humanitarian aid they would operate on a model like Doctors Without Borders, the World Food Program, etc. "Aid" is offered conditionally to countries that are in line with American interests and or countries that are in line with international finance via the IMF and World Bank, both American created institutions that enforce debt bondage for the benefit of the global north at the expense of the global south.
Real humanitarian aid is unconditional, it is without overwhelming force, it is without debt bondage, it is without empire. Palestine is under famine threat right now, America won't lift a finger beyond little token gestures. America actively embargos Cuba even though Cuba does literally nothing to anyone.
What actions can I remember and what are their outcomes of late?
America invades Iraq and destabilizes the entire region creating ISIS in the process.
America invades Afghanistan and fails to create a lasting democratic government, instead leaving the country to the Taliban which America created.
America Kills Gaddafi and starts a Civil War in Libya that is ongoing.
America intervenes in Nigeria in 2013, Nigeria is still unstable and just had a military coup in 2023.
America intervenes in Somalia and there's still a civil war there today.
America helps Saudi Arabia genocide Yemeni people starting in 2002 and is still fighting the same group it was then.
America coups Haiti over and over and over again and prevents revolution there literally for centuries instead funding its gangs and corrupt governments repeatedly.
The list really goes on and on and on. The Yugoslav war might be an exception if it weren't for the fact that America like always took advantage of the situation. Serbian forces needed to be stopped from committing genocide but the US was also involved to protect American interests as it had been pushing for capital flow from Yugoslavia in the 1980s directly through American banking institutions and had helped along the destabilization of Yugoslavia to begin with throughout the cold war despite Yugoslavia's non-aligned status.

There's a lot of nuance in all of these cases but the nuance always points back to American policy being a causal factor of instability even if it's not the only factor. In the vast majority of cases American intervention outright leads to a worse outcome than simply not being involved.
