The guy was in the UK for about 2 years before he fled to the Ecuadorian embassy, the initial court hearing was in Feb 2011 (he was in the UK for some time before that) he didn't ended up in the Embassy till late June 2012.
If the US wanted to "abduct" him doing it from within the UK which is both a 5-eye country and a general close intelligence and law enforcement proxy of the US would've been considerably easier.
In fact he was under UK "custody" for several occasions during the hearings (and before it got to the Supreme court I don't think it even received media attention) he could've been easily whisked away to some CIA chartered jet as you claim at any point.
The US doesn't want to get him on BS charges, the US also doesn't want to put him in gitmo it would serve no purpose for them if they'll ever go after him they'll do it openly and with every smoking gun known to men and try him in public anything less than that is going to be utterly pointless and counter productive.
