What can the US do to make up for the invasion of Iraq?

Majority of Arabs States are Sunnis and they are not happy with Shites being incharge in Iraq. You cannot bring peace or win in Iraq by supporting Shites.The only thing United States is doing by encouraging Shites in Iraq is Strengthening the influence of Iran and making other Sunni Arabs very unhappy .And that is NO GOOD.SO STRAT DEALING WITH SUNNIS IF YOU WANT TO TURN THE THINGS OVER.
