Well you have a habit of posting silly optimistic things I guess.
But since I seem to have offended your delicate sensitivities I'll clarify for you:
To say we do "everything" we can to avoid civilian casualties is a little disingenuous. We take what I would consider an appropriate level of precautions, but it seems there is an accepted level of doubt vs reward that will always end up with innocent lives being lost. Couple that with an unwinnable war that, imo, serves no purpose, I'd say your POV is extremely optimistic.
Given the bombastic and completely undiplomatic twitter rantings of our president, I'd say it's optimistic to assume we won't share a whole lot of the blame if the North Korea tensions come to military action.
