What does everyone expect to be our next war/conflict?

Considering everything that's going on with ISIS and the recent terrorist threats and attacks around the world and on US soil, is there a fight to be had there? Any reason we would be in a war with Russia soon? Invading Crimeia (Ukraine) is definitely something that should've been stopped.
And with the presidents cabinet acknowledging that China has been spying on us, is that an indication that conflict may arise there?
