[Kingsman] The Kingsman can't be made public for saving the world. Did people not notice the whole world becoming homicidal? Whats the aftermath of the movie?

Obviously the sim cards had to be destroyed after the movie due to what they could do, and nearly every world leader is dead now. Someone had to be behind it all, and someone had to have stopped them.

You'll remember that Valentine had kidnapped many reputable world leaders and celebrities who he felt would be required to get certain political geographies back on task, such as the Princess of Sweden that our lucky hero got to spend an evening with at the end.

So while Kingsmen can't come out and explain what happened, the people they *rescued* can come out and say "Listen, we were kidnapped by Valentine, he used those sim cards to make everyone insane, but... Let's say the UN... managed to stop him shortly after it all started. Sorry it took so long, red tape and all that of bureaucracy."

While there would be much chaos in the following few months, humanity has this pretty awesome record of banding together and recovering from massive disasters when they're finally forced to. The world is now run mostly by more humane politicians who care about the people they preside over instead of money and themselves.
