The invasion of Iraq had nothing to do with Afghanistan.
The thread is "Iraq war worth the cost?".
Cain said "Can anyone think of a better way to spend trillions of dollars than killing tens of thousands of people (if not hundreds of thousands)? "
You said
"Terrorist's fault. "
I pointed out Bin Laden and al Qaeda had nothing to do with Iraq. You have not actually linked Iraq to Afghanistan. After 9/11, and the revelation that Afghanistan under the Taliban was refusing to give up Bin Laden and Al Qaeda, I don't think many people were surprised that the US invaded Afghanistan.
What surprised a lot of people was the invasion of Iraq, and the clear revelation that Afghanistan, Al Qaeda and Bin Laden were just a minor consideration to the US under Bush and PNAC. The major weight of force (and cost, if we refer back to the topic), was to be spent on Iraq. The war in Afghanistan is still under resourced, in it's current form it cannot be won, it was up to Obama to finally run down Bin Laden, the US has been hobbled by the war in Iraq, it simply cannot afford to allocate the resources to Afghanistan to force a win.
