A Deeper Color

Maybe starting another world war after the first one or a cold war would be inevitable or even further, necessary incidents but not World War II and the Cold War. 
The mentioned wars of the 20th century were due to evading smaller wars by the Western democracies. Emergency measures against Nazi Germany during 1933-1937 might be ended up with war but it could probably prevent the Second World War and its uncountable consequences. It is about the same for the Cold War; the conflict took place very late, given the fact that Stalin's industrialization was almost completed so that the Nazi Germany invasion of the Soviet Union could not stop that. For sure, beating the hero of Brest-Litovsk was easier than taking the Cold War.
After the First World War, the West needed to concentrate on its reconstruction but it cannot be ignored that sometimes it is not buying time but letting a wind to become a tornado. 
Accordingly, every threat, whether internal or external must be neutralized.

Conformists: Death Takes All

For years being conformist has been a secure and comfortable means to get some power without any trouble. They are not dangerous at least until they play by the rules but the fact cannot be ignored that they are loyal to nothing and also do not believe in anything but themselves. Therefore, they are potential threats since they can be forces and fuels of any possible coup while the conformists do not raise any specific objection to anything until then so that they could remain as unknown devils. 
No one claims that the agents of the system intend to forgive the significant sins of human beings as mighty Jesus in order to purify the universe but indeed they are going to wipe out some sinners to clear the very significant sins from the world. 
The history of conformism and the career of all conformists within the system must be considered terminated, though it can gradually be implemented.

Shock Crisis

Crisis managing is the antidote of a crisis, which might be as a result of a shock unless the shock itself is a crisis. 
A political shock like mass resignation of a group of parliament's representatives can cause a radical but temporary effect against status quo, apart from leading to a political crisis. Crises are manageable but the very temporary radical effects can only be handled by time and patience. Now, if the number of imposing shocks against a state is more than its time capacity, the crisis of shock is formed. Parameters like the economy, population, demographics, culture, etc. determine the time capacity of a state so that an economic downfall of a state could negatively affect its time capacity. 
 It is predictable that the governments would try to resolve the crises due to shocks (such as diplomatic, economic crises, etc.), at the outset. Whereas, the governments would be suffering from lack of time over tackling the consequences and 'temporary radical effects' of the various and numerous shocks. Therefore, they would attempt to buy some time by resorting a kind of radicalism; in short, the good scenario would be something like Roosevelt's New Deal or positive shocks, while the bad scenario can end up with a version of McCarthyism or martial law. Needless to say that Tehran must be the target of this attack.
