I'm stealing this from Theo:
At the Russian military academy, a general gave a lecture on "Potential Problems and Military Strategy." At the end of the lecture, he asked if there were any questions.
An officer stood up and asked, "Will there be a third world war? Will Russia take part in it?"
The general answered both questions in the affirmative.
The officer asked, "Who will be the enemy?"
The general replied, "All indications point to China ."
All in the audience were shocked. The officer asks, "General, we are only 150 million. There are 1.5 billion Chinese. Can we win at all?"
The general answered, "Just think about this. In modern warfare, it is not the quantity that matters but the quality. For example, in the Middle East we have had a few wars recently where 5 million Jews fought against 150 million Arabs, and Israel was always victorious."
After a small pause, the officer asked, "Do we have enough Jews???"
