>Until then, he remains a once-big-fish in a small pond, living in exile and under armed guard in Beirut for the foreseeable future. How secure is he in Beruit? If Japan really wanted him badly, I would guess he would be pretty easy for Israeli Mossad to pick up.
The Mossad only does what's in the national interest of Israel, they are not bounty hunters for hire.
If Japan really wants Ghosn they will either have to send their own team with all the headaches that entails and/or they will need to negotiate with the various groups currently in control of Lebanon... and given they're falling apart, failing to secure food, medicine and fuel for electricity generation, a rich multi-millionaire with a private security force isn't exactly at the top of their priority list.
