I haven't thus far shared my opinion that the US should go into Iraq and Syria with ground troops because this board has a very isolationist bent and I didn't feel like arguing the point. The fact is, these people will only grow more powerful until they are finally taken down, and they will never, ever be taken down until western powers and/or perhaps Russia undertakes a major ground campaign to remove them. I'd prefer that Russia did it, at least in Syria, but eventually we are going to do it if Russia does not.
What is happening in Paris is going to happen in the US eventually, and my bet is sooner rather than later. If it is a major attack with dozens to hundreds dead, at that point we won't have a choice. We may as well do it before it happens.
Those who think we'll be safe if we do the opposite and stop bombing them are naive. If we stop, they acquire more territory and only get stronger. We know the Arab armies are too weak and incompetent to take them on. It can't possibly do anything but get worse without western intervention, and the violence certainly will not be confined to the middle east.
They are already no ordinary terrorist group. They have billions in oil revenue and over 10 million people under their control. This isn't a state sponsored terrorist group - this is a terrorist state, and they will not stop killing people, both Muslim and western, until they are destroyed. These people are from another century. They want to murder everyone non-Muslin and every Muslim not practicing their version of it. These people do not belong in this world and need to be removed from it.
To be clear, I don't want to nation build in either country. I want us to go in with an overwhelming force and sweep through their territories on a search and destroy mission, then go home. This is what we should have done in Afghanistan in 2001 but which Bush was too incompetent to understand, and it's what we should do right now in Iraq.
And the fact that Bush's disastrous Iraq war had a hand in creating a fertile environment for Isis only strengthens the argument here. If we are partially responsible for the death and misery these people have wrought, then it is our moral obligation to clean it up.
