honestly,i never hear about this,and this is shocking me

if america have debt as much like that,than from where they loan it?anybody can tell me?i never think before that a big country also have debt,and they also give some loan to other country,it cannot believe..

At the moment they borrow it mostly from American pension funds and some bond funds. They also borrow about 1/3 from foreigners. FED also lends a lot.
