Good, there was nothing that needed confronting.

Iran's regime sucked (still sucks), to be sure. This was frankly not all that much of an issue for the US. It was a big issue for other Arab nations in the area (not to mention for Israel), but I'm not sure why we should be doing their dirty work.

If the end result of all this is a large weakening in Iran's regime, a reduction in Iran's influence in the region, and (otherwise) a return to the status quo, I guess that's something of a victory. But it's far from clear that we'll even come out that well, and meanwhile we've murdered civilians, and spent American lives and war materiel. Not great. We should have left well enough alone.

"Iran's regime sucked" because they kicked out our western puppet? or is it because Iran is a a democracy, unlike "other Arab nations" (by the way iranian are as much arabs than you) or Israel ? (Note that I'm not fan of Iran culture, but I'm not fan of ingroup cultures either).
