The reason these people proliferate is that we don't do what we say we're going to do. We don't live up to our values or follow through on our promises.

Western civilization has lost the ability to build anything positive since the neocons took charge.

The op makes a case that these groups should be eradicated because they there is no limit to the evil they would do given the power,

YET

I wonder if killing 2 million Vietnamese in their own country is not extreme evil, I wonder if indirectly killing 500,000 children in Iraq because of a decade of sanctions is not extreme evil (remember Albright said these children's deaths were worth it), I wonder if directly killing 100,000's of Iraqis just to get control of their oil in the 2003 invasion is not extreme evil?

We all agree those 3 groups the op has mentioned are bad, they could very well be evil incarnate, but lets be honest for a second, all these groups combined with their evil acts have killed just a small portion of people compared to how many America has killed over the years.

We need to fix our own backyard before we call others out for being evil, and the first step in fixing our own backyard is to arrest and try those officials still alive who have been responsible for 100,000s of deaths around the world.

If it were that easy to just press a button and only the bad guys would all vaporize instantly into the Sun, sure I'd do it, but that isn't happening any time soon. This isn't an 80s video game where things like that happen.

The OP obviously has a fundamentalist view of the world.

There is no justification for "eradicating" any group.

...kill Isis's leadership, organizers and funded.
It doesn't matter who kills them; providing targeting and intelligence to Assad on Isis should be done

We can aid a little, but without that regional determination... they're not going anywhere.
