In what way has the United States remained out of european affairs up until this time?

Historically, the United States adopted a policy of isolationism, particularly evident from the late 18th century until World War I, prioritizing domestic issues and avoiding entanglement in European conflicts. This approach was rooted in a desire to focus on national development and to steer clear of the political complexities of European alliances. Even during the early years of the Cold War, the U.S. was cautious about direct involvement in European affairs, preferring to support allied nations through economic and military aid rather than direct intervention. However, this stance began to shift significantly post-World War II, as the U.S. became more engaged in European politics to counter the spread of communism.
