IMO, we move next against them as priority-one commencing February 1. Not saying militarily first. But the priorities have probably already been set:
1) Subdue Iraq,
2) Pressure the EU/UN to go after Iran,
3) Pressure China to go after NK,
4) Pressure Israel to make peace with the Palis,
5) Go after Syria HARD,
6) See what happens in Iran, revise the plan A/R.
