Bush signed off on leaving Iraq. That's a fact. Obama followed the Bush agreement. One of the big hangups that led to the troop withdrawel was the Iraqi government wanted to right of the Iraq's justice system to prosecute American troops for serious crimes. America's conservatives did our troops be subject to Iraqi arrests/trials/punishment. Iraq's Parliament voted with an overwhelming majority for legislation demanding all troops to leave according to the Bush-al-Maliki.
Also, prior to the invasion of Iraq, the Bush Administration was warned of the high possibility of a Shia-Sunni Civil War by two of his own intelligence agencies. One of the main reasons of the creation of ISIS was the al-Maliki's government minimizing Sunni involvement within Iraq's government.
Just a few facts to add to the conversation.
Can you imagine the field day the Obama haters would have had if Obama had kept us in Iraq?
The American people didn't want us to stay, the Iraqi people didn't want us to stay, the UN mandate was running out, the Iraqi government didn't want us to stay,
but NOW the Obama derangement crowd is trying to make the argument that against all that,
Obama was supposed to somehow force an American occupation extension on Iraq.
btw, and for what? To add a few thousand more American dead to the toll? The warmonger Right must be shown for what it is.
