Basra is reasonaliby stable compared to the rest of Iraq. Yes, the is still trouble, but the Iraqi forces there seem ready to take over. The Iraq's were told when things were stable and Iraqi forces were ready to take over, that they would hand over power and withdraw.
I believe in the last couple of months they have done less patrols, letting the Iraqi's do it themselves. For the sake of all there, I hope the region stays stable.
