Early in 2003 Schwarzkopf made a public statement saying he would prefer to give the U.N. more time and to build a larger coalition...nothing more as Chamberlain buff here implies.
And since that public statement, Schwarzkopf has not made any others regarding opposition to the war.
I suspect the General has moved to our side on this, or at worst he knows better than to undermine the troops in the field by proclaiming their mission to be a failure when they are actually succeeding brilliantly. Some folks could take a lesson...
