1) The question is moot because no one wars are fights this way anymore. (actually, in war, no one ever fought this way. Where are the throat, eye, groin, strikes, the biting off of noses.....)
2) If a war was fought with say swords and spears, the numbers would matter, whoever has the numerical superiority would win.
Well armed, I by myself could defeat both these sides put together.
Lesson to be learned:
the Muslims have the numbers, but they are not united and never have been. That is why Israel has prospered all these years and controls the Middle East, despite being surrounded by Muslims.
the Chinese Communists have a standing army of 200 million, they have a lethal nuclear arsenal, navy, air force, industrial base, and the capital. They are the real enemy.
