You just answered your own conundrum with that part I boldfaced.I doubt that the majority, at least, of anti-Iraq war protesters were complete noninterventionists who believed that any stuff that interferes in other people's business (like the police system, or even the hospital system (why you are giving that medicine to him? It's his business if he's gonna die without it, not ours!)) is morally wrong. I think that, althrough they were opposed to the war before it, and, therefore, before any repercussions had a chance to begin, they had the brains to predict some of the repercussions.
You're wondering why God doesn't wipe all suffering from our lives? Maybe it's because He knows what the repercussions would be if He did?
One of the more common themes in sci-fi stories (particularly time travel) is that you shouldn't mess around with history because it does long-term damage. That British time traveller who flies around in a phone booth that's larger on the inside than on the outside? You don't see him running around stopping World War II or trying to prevent the evil Daleks from ever being created, because the outcomes from those interventions are even worse than doing nothing. World of Warcraft has this one screwball quest where some superpowerful entity messes with time and prevents the First War between the orcs and humans from ever happening--the result is that both orcs and humans go extinct because the lack of war makes them too weak to defeat a future foe much, much worse than each other (the point of the quest is to prevent the superpowerful entity from interfering in the timeline to begin with). And one of my favorites is a story about an alien race that tries to destroy humanity by going far into Earth's past and crashing an asteroid into the planet to destroy all life upon it. Guess what--those aliens went back in time 65 million years, and the asteroid they smacked our planet with turned out to be the one that CAUSED the human race to come into being in the first place! They tried to wipe us out, and their plan backfired completely.
Seriously, dude, get out of that cancer-causing sun, sit down and read some science fiction.

(The truth is out there.....
