My guess is we have a 3 step plan so as not to face two fronts at the same time. Step is get Iraq self sufficient. Step two is aim our military resources towards Syria. Some fighting but Syria collapses politically. Our rear and flank are secure. Step three - aim our resources at Iran. Big fight but Iran collapses politically. Peace starts taking hold.
I read that a general was asked how long it would take to take Syria, and he said 15 days, one day to take it and two weeks to stop laughing.
