A little patience is in order here, and a little perspective. Building a new government from the ground up takes time. The bombings are distracting the press from the fact that important progress is being made toward that goal. So far, we have suffered fewer than 300 casualties since April. If this were Vietnam, we would be losing a thousand a month.
While a June pullout MIGHT be a little premature, it is not an unrealistic goal.
