Ban profiting from warmongering

I just saw a news clip about how the Israeli military industrial complex has, for all intents and purposes, designated the Gaza strip as the testing site for their products of warfare. I have previously written “…economies exists to advance the survival, well-being and growth of all its participants.” An economic sector whose products do the opposite and who very coldly sets aside a densely populated geographical area as grounds to test the effectiveness of their killing machines runs completely counter to the purpose of an economy. Because self-defense is occasionally necessary, arms production cannot be banned but profit should not be made from widgets which kill en mass. It is immoral and anti-economic.
