In the pic they look Indian so I suppose their response to you in Hindi would be "Kya tiklef heh, mader choad?"
Honestly, I hardly have any problems with USPS but when the time comes that they may mishandle a piece, insurance is a good thing.
'Course it doesn't help that the US Gov't laid off some 7500 USPS employees in recent months. Some of them "monkeys" were probably necessary in ensuring your pieces get to you safely.
.. also a pretty good argument for not shipping international.
