I strongly supported the initial invasions of Afghanistan and Iraq, but learned my lesson on “nation building”. A nation either has their own Jefferson, Madison, and Adams or they don’t. These (and other) third-world crap-holes with warlord tribes will never exit the 9th Century by external means. Liberty blossoms from the civil society, not the tip of a bayonet.
Get out, and stay out!
I was supportive of GWB in his military plans too, but I doubt I will ever be in favor of large scale, “boots on the ground” actions ever again, except when the US has absolutely no choice. The reason being, our politicians won’t fight to win, and win quickly. They dither and shilly shally along with half measures for years and years while our people and our allies get killed and maimed, and our money goes down the drain.
There was no "nation building" involved in Iraq. The Iraq war was a success until Obama came into office and withdrew all American support which was contradictory to the President Bush plan...........As far as Afghanistan, I have no comment.
So why are we going back? Bears repeating get out and stay out.
