More often than most people think.
Take the Tienanmen Square massacre for example, you had a world that's watching communist countries overthrow there governments with riots and civil war spreading like wildfire.
You have China, a nation with the worlds highest population, that's being kept in order by a bumbling group of Fascists (the party).
Suddenly protests begin, protests that appear very similar to the ones that lead to communist regimes being deposed in former soviet states.
So what did they do? Well we all know.
Its easy to look at this event from a humanitarian perspective, claim that the murder of hundreds of protesters in the name of 'keeping order' cannot be justified.
Protesters which began to openly attack military personnel, jumping on armored vehicles and hitting them with sticks.
But think for a second, if these protests had continued and escalated, what then?
Would the party be overthrown? Would the worlds most populous police state lose its police?
Would it descend into all out civil war? Would this divided China be able to re-unify or would it fall to pieces? What would the death toll be then?
I don't mean to say that they were necessarily correct in there actions, but there's a lot more to it than meets the eye.
And that's why they should have beaten those protesters in Thailand.....wait what were we talking about?
