Radical idea: to get him out of the Ecuadorian embassy and eventually on with his life

The alternative was him being locked in self-imposed exile forever. By getting him out, extraditing him, and finally sentencing him to a min term sentence, they can say they did something and still let him go in a reasonable amount of time.

I do not see /s tag so I am extremely confused.

Why would USA do this?

Since when has any country acted with benevolence towards those individuals it deems its enemy?
