Gov't budget and import/export of currency has nothing to do with each other.
Current account deficit is what I wanted to type, not only trade. It works like this since Bretton Woods (okay, 40 years ago): US has current account deficit, that means that US dolars (or bonds in USD) are collected by other countries, and the US receives physical values (traded goods, raw materials, etc.) in return. When the USD loses value vs other currencies, the other countries posess now less value, because the USD they own is worth less physical stuff/other currencies.
The US is trying hard to do the same thing with China currently, since China has bunkered some 3 trillion USD. Devalue the USD a few percent vs the Renminbi and the US has saved a lot of value it would otherwise have to "pay back" to China some day.
Its a good thing to run the leading international currency (ie the USD) because of the implicit value transfer to your own country.
