Dov - the chances of me me transporting sealed packages across USA borders for 3rd parties are presently rated between ZERO and ZERO minus. @:-)
To explain to some nice US customs man in LAX:
"this Guy from Beirut gave me this sealed box for this guy in Israel, and trust me it will all be fine and dandy to take on this large shiny US legacy carrier plane" is not going to happen any century soon.
And if it were in reverse it is
STILL not gonna happen. ;0
