Ofcourse brother, i agree with you, we should prepare for war and use strategy, it was the way of our beloved Rasoolullah. But I get angry when I hear that we lost because the enemy had superior technology, and when people start glorifying the kaffirs. Thats not the reason, we lack taqwa and we are not steadfast. Thats why Allah doesn't give us victory. We will come out victorious. "Our Lord! Pour forth on us patience, and set firm our feet and make us victorious over the disbelieving people." (Al Baqarah: 250 ) Ameen.
