The terrorists caused mass killings. That was their aim. Was it murder? Yes it was deliberate attacks against civilians.
That is true. They deliberately flew those planes into buildings that the knew people were in.

Are our cruise missiles deliberately directed at civilian targets? hardly.
WTF? We are deliberately aiming them at buildings that we know people are in.

It is the EXACT same scenario.

They use planes.
We use missles.

They target buildings occupied by civilians.
We target buildings occupied by civilians.

They don't care about the people being killed.
We don't care about the people being killed.

They spent lots of time planning the attack.
We spend lots of time planning the attack.

Those are the facts.

We are NOT doing ANYTHING to AVOID civilian deaths.

We ARE setting up our attack in such a way that it will ENSURE civilian deaths.

Yet there IS a way where we will NOT kill ANY civilians AND WE ARE NOT TAKING THAT WAY.
