Oh sorry... too busy sucking up to Islamists... and a communist in White House dosent help either...
Because Clinton bombed them, so he must have been right to do so, against much protest from the Russians, who were 100% right in this case.
Clinton is completely responsible for creating this Islamic hell hole, gateway for Islamic Jihad into Europe, hub of slave trading of kidnapped white western females, sold as sex slaves to Saudi sadist and snuff clubs.
That wasn't Clintons only blunder. He's responsible for the mess Haiti is in as well, because he overturned a pro American legit government an re-installed Aristole.
Sorry, kronos, but better question:
"Why isn't the US standing up for Americans?"
We've got a nationalized healthcare issue here in the US where 52% of the population is against this plan, and both President Obama and Congress are still trying to ram it through. They are calling anyone against the plan, "Right Wing Terrorists", and are literally hiring paid shills to show up at townhalls to act like their supporters.
Our government no longer cares what we think. The US is no longer a government "of the people, by the people and for the people". Our population has turned fat, dumb, lazy and passive about anything that government wants to do -- to us and, unfortunately, to you.
In short, we are all screwed.
Why are not United States standing up for Serbs?
Because it was the (elected) leaders of the Serbs who decided that they'd be happier living in a world without Bosnians.
