What is the difference between non-interventionalism and isolationism as foreign policies?

Question

I've seen a lot of confusion about what the difference is, and if there's any difference at all. Can anybody please tell me what the difference is between a foreign policy of non-intervention and a foreign policy of isolation? In terms of trade, military actions, and diplomacy. Relevant examples would be welcome.

Answer 1

Non interventionism does not exclude trading, talking or even being friends with other nations. It simply means no allegiances and only war when another country attacks or threatens the US, no policing the world or nation building. Isolationism is non intervention plus economic protectionism to an extreme degree and not talk to other countries, even if they ask or request trying to avoid any involvement outside of the USA.

Non interventionism is like a selfasured peaceful independent attitude, we're cool with everyone, just do our own thing no offense. Isolationism is more, leave us alone, nothing good can come from anything non American

Answer 2

"I will not wage a war on you", vs "I do not want to talk to you"
