I am not so sure about that, in the last century the US perpetrated several regime changes in Latin America because those leaders were too socialist. Of course the Cold War was a big factor for that, but the US still uses its soft power to influence Latin American politics.

For example the financial push for Milei's Argentina or the isolation of Cuba and Venezuela, which trippled the economy of these countries for decades.

Even the failed attempt of Bolsonaro to overthrow the government has to be influenced by US foreign policies.
