Economic sanctions are quite obviously an alternative to war (though perhaps not the only alternative), and if you look at recent administrations proclivity for intervention and regime change, it’s also quite obviously a change of tack.

Whether the sanctions are warranted is much more open to debate. But in Syria you have a regime that created the greatest humanitarian crisis of a generation, and in Iran you have a regime that repeatedly vows to wipe another country off the map, and an enormous proliferation risk. So I know what side of that debate I’d fall on, and I know what my preferences are when it comes to starting new wars.
