Just read from this article from RawStory that the Iraq/Afghanistan war effort, over the next decade (and possibly including what we've already spent - that part isn't clear) will cost more than $2 trillion, with over $700 billion in INTEREST - because we are spending borrowed money.
No, seriously, let me write that all out:
$705,000,000,000.00 in interest
RawStory estimates that this amounts to $8000 per person in this country. And I thought Republicans were meant to be fiscally conservative. Yeah, that's right Republicans, you just got told. Feel the shame.
