I didn't find his reasoning for why Ritter et. al. are wrong very convincing, i.e. "nobody knows what the situation on the ground WILL BE when the Ukrainians launch their counter offensive next month" which has nothing to do with what Ritter et. al. have been saying (the situation NOW not predictions of the future).

It also seems to go against his later assertion that everyone is keeping everything under wraps so nobody knows anything about plans, except he's now certain that there will be a UKR counter-offensive next month.

His hypothetical leading to tactical nuclear use by Russia isn't too far fetched although there are other scenarios that could easily occur including the neo-con psychos coming up with some brilliant plan to blame Russia for something they do.

That aside, it does seem that the main point of his article is to call for a cease fire which is probably the best we can hope for.
