First, this was written by a journalist, and not a historian. Second, the purpose of the article, and the linked article from Huffington Post, is to rehabilitate Chamberlain in order to attempt to prevent perceived warmongers from using the cry of "Appeasement!" to attack the
Iran nuclear deal, a point to which
Garrison alluded above.
Further, this is a continuation of your attempt to change horses. Your original claim was that Britain would have suffered a disastrous defeat if the Allies hadn't appeased Hitler at Munich. That argument has been utterly shredded, so now you're trying a different tack: Claiming that Chamberlain made the best decision he could have in the circumstances, considering the political situation and the grossly inflated estimates of German military capabilities at the time. This is also wrong, but at least it's not laughably absurd, like your "Britain would have been defeated in a week in 1938" assertion.
However, for whatever reason, you are apparently unwilling or unable to admit that your original claim has been destroyed, so you merely ignore the refutations and continue ducking questions you can't answer.
