We Muslims do not need to learn from bloody israelis or americans. The reason the Muslims were a defeated Ummah is the lack of Taqwa and attachment of Dunya. Best example is Battle of Badr, the Mushriks had 1000 odd soldiers with the best of weapons and technology. But the Muslims were ill equipped and a little over 300 in number. We defeated them in a matter of hours. Now, Allah has lightened [the hardship] for you, and He knows that among you is weakness. So if there are from you one hundred [who are] steadfast, they will overcome two hundred. And if there are among you a thousand, they will overcome two thousand by permission of Allah. And Allah is with the steadfast. (Suratul Anfal: 66)
