Can you ethically justify joining the military (USA/UK)?

I was just wondering whether it's possible to ethically justify joining the military. I am interested in the type of responses people make.

By just war theory, neither nation has fought a just war since WWII, so it’s not easy to see a way to ethically serve in their militaries.

There are some bankshot-type arguments you could make — I’ll do a better job being a moral soldier than whoever would replace me — but you have to start from a position of defending participation in unjust wars.
