President Obama pivoted to the Pacific based on his claim that he "responsibly ended" the Iraq War.
Which is amazingly similar to (now deceased) Representative Murtha's plan for Iraq at the end of 2005 when that fight raged:
Now, my plan says redeploy to the periphery, to Kuwait, to Okinawa, and if there's a terrorist activity that affects our allies or affects the United States' national security, we can then go back in.
So we did redeploy out of Iraq, and we do have a presence in Kuwait. While Okinawa is part of Japan and not on Iraq's "periphery," we did pivot to that Okinawa region, making his plan good enough for government work.
So, do we have enough terrorist activity in Iraq now to justify going back in?
