IMO the denial of Sweden to guarantee Assange that he will not be sent to the US is enough to

217. No, it really isn't

I don't know why you think it's acceptable for a sovereign state to abrogate its treaty obligations to another sovereign state in one particular instance. Sweden and the US have an extradition treaty, which stipulates which offences are extraditable and which are not. Among those that are not are political crimes. If Assange is properly charged with a crime under US law relating to his disclosure of classified US materials via Wikileaks, and a warrant is issued, Sweden has the right under the treaty to ajudge it a "political" crime and refuse extradition. Which is highly likely as Assange is not a US citizen and Wikileaks' servers were not hosted in the US. But a blanket statement or promise by Sweden that they will not extradite under any circumstances? That would undermine the fabric of international diplomacy and the basis of existing treaties. It's a fantastically stupid thing to suggest.
