The US Marines are suggesting that they be redeployed from Iraq to Afghanistan.
With about 25,000 Marines in Iraq, and about 26,000 soldiers in Afghanistan, this would seem a relatively straightforward swap, though the obvious question is, “why?”
I think that it is because the Marines as a group recognize that Iraq as a lie, and while they are willing to fight, they find that fighting for a lie is disheartening.
There is some push back on this, particularly from the USAF, because the Marines bring their own air capability, one that would probably seriously outperform the USAF, since a Marine air wing is more focused on the ground, with every pilot being a trained rifleman, which would mean less civilian casualties, and better coordination with ground troops.
