This war has also made me change my perspective on working on weapons, etc. I've always been more of a "how could you justify spending your life working on weapons?" person, but after Russia invaded and started a needless war, I've been thankful that the US and others have been able to provide weapon systems for Ukraine to defend itself. I wish we lived in a world where weapons development was unnecessary but as long as madmen like Putin can single-handedly order a senseless invasion, we obviously need to be well armed.
