Interested to know you see the drone strike app as a left issue? I don’t think opinions on foreign intervention fall very neatly along the left-right spectrum
The right is much more inclined to agree with the characterization that it's mostly terrorists we're killing or that why are civilians around them.
To what some on the right might object is why are we spending all this money on this, which they might even arrive at ultimately the same conclusion as the left but for a different reason.
