I’m not saying they didn’t have weapons, nor that they should have used weapons. I’m just challenging your belief that we can be victorious even if G-d wants us to be harmed. I think it is absolutely apikorsos for a yid to think “If only we had better weapons the beis hamikdash would be standing today” The gemarros discuss why the beis hamikdash was destroyed, and the neviim at the time told us how to prevent its destruction, how THROUGH TESHUVA AND TORAH!!
How come Paroh, Haman, the greeks etc. were able to inflict their wrath on Klal Yisroel? Because they were stronger? Because they had better weaponry? NO!! because Klal Yisroel did aveiros that led us to be punished by HaKadosh Baruch Hu.
The fact that you believe these things were avoidable with better weaponry basically shows me that a discussion with you would be an exercise in futility.
By the way, Shlomo HaMelech says something about your opinion: ??-????, ??? ?????, ??? ?????, ??? ?????; ???? ?? ???, ??? ????
