I never stated that was in preperation for war and I specifically stated that I did not view it as an act of war. I was merely pointing it out to show that the scenario that you layed out above in reality happened in the reverse.
I am claryfying something in my last post to show I meant Russia not just the soviet union had a history of imperialism. Yes the boxer rebellion was under the Tzars but the Soviet Union had a huge land based empire all the way to Korea and they suppressed any seperatism. So how is that local and not intercontinental?
I am in no way trying to say the United States had to act abroad. This post started as specifically a question about US taking internal security measures against soviet espionage.
I do think it is odd that I am being attacked for equating the Soviet Union to an intercontinental empire when it most certainly did not have to act that way just as most people would assume for the United States.
Lets say the USSR was an aggressive empire abroad. To many that does not mean the United States had to get involved as long as its borders are protected. By that same measure the USSR should be held too.
