I am wondering how hard it would be for the CIA to pay someone to make an accusation? It need not involve a conspiracy between governments. You pay someone to make an accusation, press charges or find some other way of applying pressure and let the other government respond to it.

Look at who you'd have to have on board for something like this:

Do you need the prosecutor on board? Not if he thinks the allegations are true.

Do you need the Swedish government on board? Not if they believe the allegations might be true.

Do you need the alleged victim on board? Yes. This is the only one you really need on board to do such a thing.

Are we talking about the same Sweden which had lax laws on copyright but upon pressure from the United States (including threats of trade sanctions) ended up arresting The Pirate Bay founders?

Are we to understand that Sweden has not charged him? Why then are they trying to extradite him?
