so how would the indiscriminate use of weapons against non-combatants in built up areas aid anyone?
Have you ever heard of FIBUA in empty cities ? Falluja without arty, how many more US KIAs?
In Vietnam the US tried this option in Hué. 216 US KIAs, over 1,500 US WIAs.
Those that are the main culprits never sign such treaties that are virtue signalling PR exercises led by nations that never engage in real combat operations.
What's next ? Maybe Austria could ask for a ban on submarines as it has no navy....
