Well, retired Gen. Jack Keane--a Fox News contributor, and a very smart person, in my view--said the following today:
Ukraine would not surrender after one bombing; so the Russians would try several more.
And the Ukrainians still would not surrender.
And Russia no longer has suits for its personnel to wear, that would make them impervious to the radiation there, were they to go in.
