> I think historically the US has actually been quite good at ensuring stability in other countries.

I'm now unsure whether your meaning of "stability" is equivalent to my meaning of "stability". I'm curious what is your basis for this thinking and whether you have a factual basis for "has actually been quite good". What measurement statistic would be reasonable to use for measuring that? Lets re-visit some counter facts that will be likely to be raised. How would you quantify these in opposition to your claim?

In Argentina, military forces overthrew the democratically elected President Isabel Perón in the 1976 Argentine coup d'état, starting the military dictatorship of General Jorge Rafael Videla, known as the National Reorganization Process. Both the coup and the following authoritarian regime was eagerly endorsed and supported by the United States government[5] with US Secretary of State Henry Kissinger paying several official visits to Argentina during the dictatorship

The US government supported the 1971 coup led by General Hugo Banzer that toppled President Juan José Torres of Bolivia.[9][10] Torres had displeased Washington by convening an "Asamblea del Pueblo" (Assembly of the People), in which representatives of specific proletarian sectors of society were represented (miners, unionized teachers, students, peasants), and more generally by leading the country in what was perceived as a left wing direction. Banzer hatched a bloody military uprising starting on August 18, 1971, that succeeded in taking the reins of power by August 22, 1971. After Banzer took power, the US provided extensive military and other aid to the Banzer dictatorship.[11][12] Torres, who had fled Bolivia, was kidnapped and assassinated in 1976 as part of Operation Condor, the US-supported campaign of political repression and state terrorism by South American right-wing dictators.[13][14][15]

US-backed[16] 1964 Brazilian coup d'état against social democrat João Goulart. Under then-President John F. Kennedy, the US sought to "prevent Brazil from becoming another China or Cuba", a policy which was carried forward under Lyndon B. Johnson and which led to US military support for the coup in April 1964

After the democratic election of President Salvador Allende in 1970, an economic war ordered by President Richard Nixon,[19] among other things, caused the 1973 Chilean coup d'état with the involvement of the CIA[20] due to Allende's democratic socialist leanings. What followed was the decades-long US-backed military dictatorship of Augusto Pinochet.

Peasants and workers (mostly of indigenous descent) revolt during the first half of the 20th century due to harsh living conditions and the abuse from landlords and the government-supported American United Fruit Company. This revolt was repressed, but led to the democratic election of Jacobo Arbenz. Arbenz was overthrown during the 1954 Guatemalan coup d'état, endorsed by the United States

In 1912, during the Banana Wars period, the U.S. occupied Nicaragua as a means of protecting American business interests and protecting the rights that Nicaragua granted to the United States to construct a canal there.[38] The intervention, utilizing the U.S. Marine Corps, was sparked by a rebellion that opposed the United States. After quelling the rebellion, the U.S. continued occupying Nicaragua until 1933, when President Herbert Hoover officially ended the occupation.[39]

After the Sandinista Revolution that overthrew pro-American dictator[40] Anastasio Somoza Debayle, Nicaragua fought the Contra guerrillas supported by the United States.
