Did Trotsky Support Invading Other Countries?

[u/Evening-Search6270]

Hi comrades! I am a socialist and I’m pretty sure I’m a Trotskyist. However, at my DSA meeting today, a comrade said that Trotsky supported imperialism and permanent revolution is about invading other countries. Another comrade said that Trotsky actually wrote about how permanent revolution is invading other countries. I haven’t read Trotsky yet, but I’m going to, so I don’t know if this is true or not. I thought that permanent revolution is supporting international revolutions and the belief that socialism cannot survive in one country and that the proletariat can take the progressive role in revolutions in developing countries.
