Weapon companies and manufacturing.

With the war in Ukraine raging and countries donating aid and weapons, there's a shortage of weapons and in some countries the shortage are severe. It has me thinking about learning and getting into this area of stocks and trading. As more demands increase the goal is to make profit.

I have come for advice, is my thinking on point? That investing in manufacturing weapons companies for profits at the end?
If it is a good idea where do I start learning the ins and outs so I know how best to add it to my portfolio and move forward with my strategies with my other stocks.

Currently have no positions as I'm still in the research and brainstorm phase. And looking for a reality check on if its a good or bad idea trading/investing this area as well as the best place to start. As this is a new area.

I understand some may not like this discussion and I sympathise with its morality. However, let's keep this on topic on stocks.
