In this case, you feel that war is a grim necessity, and also admit that this is a military device. If your country is in a war, wouldn’t you want to be on the winning side? Culture often doesn’t survive losing a war.
If so, then I don’t understand why people are against development of this tech. If you’re on the battlefield, you bet that you’d want a way to take out the people shooting at you from the hill on the other side. Usually that means calling in air support. Here, your air support can be almost pocket sized.

Would you want to fight a war without guns? Because it sounds similar to an argument against developing guns.
