To summarize this video, if I followed it correctly:
Stage 1: Demoralization: 15-20 years is what it takes to educate one generation of students and expose them to the ideology of the enemy. Bezmenov says this process was completed (by time of interview).
Stage 2: Destabilization: 2-5 years for the economy, foreign relations, and defense systems to be destabilized.
Stage 3: Crisis: 6 weeks to bring a country to the verge of crisis.
Stage 4: Normalization follows violent change of power, structure, and economy. Big brother government. Normalization lasts indefinitely.
Looks like we're at Stage 4 now, except the change of power here wasn't violent.
Can you imagine if Obama had not been elected - there would have been violence I assure you his followers are useful idiots
