Explanation:

The Red Brigades were an Italian far - left terrorist organization. Their main goal was to create a revolutionary state independent of NATO through violent means. Robberies were methods they used, not the main goal, and assassination was a tactic, not the overarching aim. Establishing an independent nation within Italy was not their main goal.

Answer:

to create a revolutionary state independent of NATO
