Justin, there are no meaningful parallels, and I don't wear partisan blinders. It was always inevitable that lots of people would be killed, the only alternative was to do nothing, which was not an option after 911. Sooner or later, we were going to have to remove Saddam, even without 911, that just accelerated it.
In Vietnam, we faced an enemy backed by the Soviet Union and China, waging what amounted to a proxy battle there. That simply is not the case in Iraq or Afghanistan, at least not on anything like that scale. The end of the USSR changed the entire balance of political and military power around the world, especially in the Middle East. For example, it's the absence of the USSR that makes it even conceivable for the Israelis to talk about withdrawals from some of the occupied territories, since the USSR's absence leaves the Arab states opposed to the Israelies without an armorer and patron.
So far, we've avoided many of the most damaging errors of Vietnam, and despite the spin the traditional media keep trying to put on it, we're succeeding more than we're failing there. Whenever something goes right, they stop talking about it. There's been a long laundry list of things that were 'sure' to go wrong in Iraq, most of which didn't. But the liberal media simply ignores the good news, for the most part, striving instead to put the worst possible spin on everything. They've done this to the point of repeatedly embarrassing themselves, such as
Newsweek (big surprise on that one) just did.
Newsweek Admits Story Was Wrong
Newsweek Spin
This is hardly the first such incident. They've tried to spin every setback and mistake (and there are always setbacks and mistakes in every war and every effort) as an unconquerable disaster, or proof of malice and conspiracy in the Bush Administration. Yet somehow things keep moving forward in spite of it.
The elections that were never supposed to happen, happened. The new government that wasn't supposed to be able to form, formed. The insurgency is killing people, but they aren't accomplishing their goals. The 3-way civil war that was inevitable by now, has yet to happen.
This goes all the way back to the immediate aftermath of 911, when Afghanistan couldn't be conquered and the military was botching the war, when we were going to be forced from Afghanistan with our tail between our legs, etc. The mountains were too harsh, our soldiers too soft, the military leadership gunshy, the public would stand for no casualties, the Arab Street was going to rise, etc.
It just hasn't happened, and the quagmire the media has kept trying to conjure up hasn't happened, either. The conditions that made Vietnam into what it was just don't exist here.
