I believe first world countries have an obligation to humanity to make tyrants their business. CMV

I believe that the US and the UK among Canada, Australia and other first world countries are obligated to make people like Kim Jung Un and Kony their business and remove them forcibly from power for the sake of humanitys best interests. It's my assumption that, to work towards a unity of mankind, we need to make an example of tyrants that cause men, women and children harm or death no matter the country or religion that's doing the tyranny, and it starts with the superpowers of the world to show and set that example. CMV please.

TL;DR. Some countries, if able, should police the world.

There are 2 problems with this view:

1) How do we decide who are the tyrants? If a majority in Iran wants an Islamic Fascist dictatorship of mullahs, do we overthrow them? How about if they elect them?

2) Every time we've tried to do this, it has ended up with massive civilian casualties, significant casualties among our troops, and ultimately has not changed things at all, because fundamentally you can't force freedom on people. They have to culturally be ready to take their own freedom for themselves. Examples: Vietnam, North Korea, Iraq, Afghanistan. 

In short, it's arrogant, impossible, and deadly to take your advice.
