Good point, though what's misleading is the idea that 'Europe' was a single military entity at any of those battles, and the impact of each battle on the opposition, which was able to re-build relatively soon after each of those conflicts, and in some cases continued their offensives. Khanate and Ottoman advances continued during those periods. Europe diversified. "Christiandom" divided itself. Indeed, the "rise of the West" was due to the fractured nature of Eueopean city-states c. 8th - 17th centuries and the associated European bellicosity. That didn't happen because of Christianity. It happened because of competition between states for wealth, home and abroad.
