Obama's policy resulted in Ghadaffi's death. His secretary of state actually gloated over it. Bush never did that. In fact he made sure Saddam got a fair trial.
Obama's policy resulted in the death of Osama Bin Laden. Bush claimed that he did not want to make a martyr out of Osama Bin Laden because that could strengthen Al Qeadas resolve. (Benghazi anyone ?)
Obamas policy resulted in the removal from power of Murbarak in Egypt which eventually led to his death. Now the victors of his non-support of Murbarak, are claiming they want to destroy the Egyptian civilizations vast historical relics. GWB would have never done that.
Obama has been supplying funds and probably weapons to terrorist insurgents within Syria. These insurgents tried to assassinate Assad with a bombing. Now all political operatives are open season (Ambassador Stevens anyone ?).
Obama has escalated the drone war and has no problem with killing innocent civilians to strike his target. GWB never took it to that extreme.
Obama's policies have resulted in terrorist organizations acquiring manpads and chemical munitions. In Libya there were too many terrorist organizations to count. In Egypt the Muslim Brotherhood took control of Egypt's vast chemical munitions. GWB would never do that. In fact, he used a vast military force to possible deal with potential WMD's in Iraq.
Obama and his drones are lying to all you progresso's. He is your worse nightmare. Have a nice day.
Forgot to add that Obama also has a hit list with American citizens on the list. GWB only had a deck of cards with no US citizens in the deck.
