Impossible! Especially a non-thesis masters.
Not likely, but not impossible either. I received a BS in Math, from a small liberal arts College in '67, and a MS in Math in '69 from UC Riverside. I did not have to write a thesis, but had to take 36 quarter hours of graduate level Math courses (two classes a day, three days a week), take a language exam, and two qualifying exams. That was it. One could pass the course requirements, by either taking four classes a quarter, instead of two, or by taking the course requirements as an undergraduate in the same school.
Also, one does not need a PhD to teach in the big universities, you just have to impress the hiring committee.
LOL! This is actually the case in every profession.
It seems obvious that, in regard to this Churchill fellow, it should be his lack of judgement under scrutiny and not his education. These fools like Churchill always act as if they are the underdog.
